A Good Cheap $300 Computer Build for 2015

Our $300 Build features a 4.4GHz overclocked Pentium G3258 and your choice of a 750Ti or the new R7 360. See our thoughts for the rest of the parts below.

Value 1080p Gaming Performance for $300-$325:

While it may not seem like a lot of money, going from our $200 build to $300 build makes a world of difference in terms of performance. In this case, it takes us from an APU build to a dedicated CPU GPU build.

In the past, I’ve heard from many gamers that it’s simply not worth it to build a PC up until $500. As a result of this build, I feel that this mentality might change. Perhaps it’s Intel’s new G3258 that makes this all possible or even that graphical performance per dollar has climbed upwards over the last few years while graphical requirements for games haven’t kept up. Either way, the Gaming PC at this price range is not only possible, it also greatly outperforms the likes of consoles in this same price range.

G3258 Vs. Athlon 750k

Even at stock speeds the G3258 performs better than the 750k overclocked in Battlefield 4, a game that should be able to take advantage of the 750ks additional cores. While this flip flops on a few games, the Intel Pentium G3258 is nearly always the winner with a reasonable overclock.

While some might point out that the Athlon 750k can be overclocked with a cheaper motherboard, the same can now be said about the G3258. This is because BIOS updates from motherboard manufacturers now allow overclocking of the Pentium G3258 on H81, B75, H87, and H97 chipsets. Considering the G3258 is found as low as $55 while the 750k is $70 at the time I’m writing this article, this decision has become an easy one.

The G3258 is the star of the show for this fight.

The G3258 is the star of the show for this fight.

How well does the G3258 overclock with a cheap motherboard?

When put with a high-end machine the G3258 can safely overclock to about 4.7GHz. Results for this may vary based upon the quality of the CPU you get and the hardware you use; however, for this build using a high-end setup simply doesn’t make sense. Instead, we’re left trying to get the motherboard that will give us the best overclock or value for the money. In the Tom’s Hardware article, I quoted above the MSI H81M-P33 was used to overclock the Pentium G3258 to a stable 4.5GHz at 1.3 volts.

This gives you an insane amount of performance for what could even be under $100. It’s a safe bet that there could be another motherboard out there that can give equal or better performance to this one at the $50 price range; however, in the research I’ve done I haven’t come across it.  This Anandtech thread should give you a very good idea of the performance testing that’s out there so far.

A Good Under $300 to $350 Gaming PC Build with Parts List:

Part Thoughts:
Intel Pentium Processor G3258
TTG Button
Incredible overclocker and will overclock with certain budget boards. A Bios update may be required for some.
Graphics Card
Asus GTX 750 Ti or
Sapphire Radeon R7 360
TTG Button
You'll get fantastic performance for around $100 after rebate from either of these cards.
Power SupplyEVGA 430w 80 Plus PSUA good value for the money. Also look for sales on the CX 430 as well as the 500w version of this same model.
MSI MATX Motherboard H81M-P33
TTG Button
A 4.5GHz overclock is possible with this motherboard.
RAMKingston HyperX Fury Black 8GB (2x4GB) 1600 MemoryNothing special about this ram. Fast and cheap. If it's not on sale, find something similar.
Hard Drive320GB WD Caviar BlueI like this series because it's reliable and cheap. You can also tripple the capacity for double the price here.

Best $100 Gaming Graphics Card for the Money Q4 2015

If you’re looking hard in this price range, then most likely you’ll find three options that stick out above others; the R7 260X, the R7 360, and the GTX 750 Ti. All of these can be found in a similar price range of around $99 after rebate. If prices are similar, the 750 Ti is probably the one I’d go with although the R7 360 has a case in very specific games. Still, the low energy output and high overclocking potential of the 750Ti will be appealing to most.

R7 360 vs 750 Ti

For a further analysis of the R7 360 vs the 750Ti take a look at the following benchmarks from Digital Foundry. They compared the R7 360 and the 750 Ti across multiple games. For their test, they tested with an i3-4130 and an i7-4790k to show the difference in FPS performance across CPUs. The CPU performance differential seems minimal.


Benchmark Disclaimer: As you can see it’s a good performer overall. These numbers are indicative of using a higher-end CPU but should still give you a good reference point since they’re using a stock card without an overclock.

If you’d like to compare the 750 Ti and the R7 360x. here’s a good source.

EVGA 430 Watt PSU

It’s cheap and affordable, but I hold no loyalty to it. The EVGA 80 Plus 430 Watt PSU is my pick for this month. Look for other options as well in the month you build this PC.

Power Supply Options Under $25 to $30:

While I’d recommend a pricey power supply for builds in the $1,000 price range, it’s hard to justify for a build that costs between $300 and $350. That being said in the $30 range you can still get a 400+ 80 PLUS certified option from a decent manufacturer.

This month I’m going with the EVGA 430 Watt PSU, but this option might change for you based upon what’s available. If you plan on expanding much in the future, the 500w version of this power supply might well be worth it for $10 more.

Thoughts for the Rest of the Parts:

Everything else for this build should meet a small budget. For Hard Drive, I recommend the Western Digital Caviar Blue series. The 320 GB version starts at around $25 moving up to the 1TB at $50.

For memory you’re ideal option here is to go with 8GB of memory. This is all the memory you’d ever need for the build and as memory seems to be cheaper per stick by purchasing in kits of 2×4, I recommend you go this route. Those who are fine sticking with 4GB of memory may be able to keep this build around $300 while those who go for the 8GB of RAM as I suggest, should end up around $325.

There are several kits that would work well for this. G. Skill Value, Kingston HyperX, and Corsair Vengeance kits have all come on sale within the last few months. If none of these are available, just find another quality manufacturer to take its place.

For your case, you’ll want to find something that’s both inexpensive and good. For my $200 PC Build and Cheap $150 gaming PC we used the Xion Micro ATX case. It’s cheap and has a lot to offer. That being said, as I’m recommending the H81M-P33 motherboard from MSI it should be known that this case has USB 3.0 ports in the front I/O while this motherboard is without USB 3.0 headers. You can get a cable to convert them if you’d like or just ignore them altogether.

Overall Thoughts on the $300 to $350 Gaming PC Vs. Xbox One and PS4:

Price and performance for this build are really off the chain in comparison to the $300 build we featured earlier this year in our top gaming computers series. If you want to extend the budget for this build, I’d consider upgrading the graphics card first before the CPU. It’s hard to not get excited for a fun build like this one but as always I’d love to hear your feedback and thoughts in the open discussion area below this page.

Which would you rather buy?

    this psu are realible to oc the proc and motherboard?

  • Ale Carregha

    Is this easily upgradedable? And also what case do you recommend if it is my first time building a PC. What screen should I use (can I use my macs?). How much does an operating system cost?

  • 4 Elements Productions

    I thought this was the $500 build? When i clicked the $500 build it brought me to the $300 build??

  • Cross Seigfried

    Is it necessary to overclock the G3258 for games like Dayz Standalone?

  • sarfrazk9

    Its good but still its not balanced . hard drive is just only 250gb and graphics card is awesome . therefore you can play all the latest games like gta v , battlefield 5 etc but the space they need, i would say that this hard drive cannot even store more than four games and then you will have to delete your old games for installing new ones and thats not good .

    Secondly , ram is also low as compared to the graphics card but yes still it makes sense as ram can be upgraded but graphics card cannot .

    But what i want to say is that the pc should be balanced rather than focusing on one thing . for 50 dollars more the same can be built with more storage and more memory and even better motherboard and processor. But still liked this build .

    For different builds refer to my site

    • Quiglin

      WOuld the fifty dollars mor take it over the $300 mark? If it would then I believe the purpose of this would be lost. Its a 300 build not a 300 – 350 one.

      • ramiro lapico

        it literally says $300 to $350 build.

  • Reda Alami-Nassif

    Is the only requirement for the power supply that needs to be 430w?

    • sarfrazk9

      430 watts is more than enough . it can be used to supply power to even higher end cards like gtx 780 or 970

  • Carl Miner

      • alyxw

        Hahahahaha Linux on a gaming computer.

  • Malachi Byars

    What Gaming PC case would you recommend for the $300 gaming PC?

  • connor

    doesn’t this mobo need a bios update before you can use this CPU? so won’t i need to use another cpu first to update the bios and then put in the g3258?

    • kamran

      The bios update is for the overclocking of the chip not to use it. If the chip and CPU match then they work
