My friend was going for a budget build and I was going to sell him my old 770 to save him some money. Anyways since he is trying to make it cheap what is the cheapest CPU he could get so that it will not bottleneck the 770? Intel or AMD it doesnt matter. I was looking into the I3-4160 for him but Im sure you guys know better.

Cheapest CPU to not bottleneck a... "GPU"

Sorry, no such CPU exists at any price. Any CPU can and will bottleneck any GPU in some workload conditions.

The i3-4130/50/60 is indeed the best value for gaming performance in its price class. If the budget can swing a bit more an i5-4460 is really versatile and represents a minimal compromise solution, as it will perform really well in all sorts of games.

PileDriver is more of a novelty alternative in the CPU market for gaming. It can work, but requires performance tuning to do reasonably well, and even after being performance tuned is still overall a compromise compared to using Haswell at any given implementation price. I would only advise doing an AMD build if the user actually...

I would only advise doing an AMD build if the user actually wants the experience of performance tuning for fun.

To mdocod, I'm on the phone so I can't reply however I will say that the i5 is not in his budget. The last one I chose for him was an and so so you think you could recommend me a cheap budget build motherboard to go with the i3 and 770?

OK thanks, also are there any amds that are the price of the i3-4160 that can compare to it or are even better? I just want to check because I've heard amd can be better for budget builds.

The FX-8310 from Tiger Direct for $115 is about the most competitive alternative to i3/i5 haswell options. It's a lot of CPU for the money if you can take advantage of it, up to ~50% faster than the i3 in highly parallel workloads (and about on par with an i5 in parallel workloads when compared at stock clocks). On the other hand, the i3/i5 are up to ~50% faster than the FX-8310 in poorly threaded workloads. For gaming, the i3 is faster in more games than the FX-8310, but the 8310 is an interesting alternative, especially for someone who appreciates going the road less traveled on purpose, and is after a sense of novelty or uniqueness more so than just going with the most popular solution.

The 8310 doesn't come with an HSF, so that needs to be considered... I think the smart implementation is to go ahead and buy a nice $30-50 HSF for it, place it on a motherboard with 6+2 or 8+2 phase VRMs (there are a few to choose from around and under $100), in a case with decent airflow, and power it with a nice PSU, all to support some overclocking. By the time this is all said and done, the price to implement will be competing with an i5-4440, and the performance will trade blows with the i5 depending on workload, with the i5 being better in most games, but the 8310 at ~4.5ghz being up to ~40% faster in heavily threaded workloads.

The msi h81-p33 has bare 2-phase VRMs. I wouldn't trust it with anything more than a Pentium G3220 personally.

I'd like to run P95 torture testing on that board with an 80W i5 and see how long before it throttles or self destructs.

FYI: I do not advise snagging the cheapest motherboard you can find. They are riddled with compromises that can effect performance and longevity.

Well my friend obviously wants a motherboard that is going to last him while he has the CPU, he wants it cheap but not so cheap that it is not going to perform well. Is the "dirt cheap" one you recommended good enough

I would comfortably use the Biostar Hi-Fi H81S2 for a very tight budget build. 4 phase heatsunk VRMs inspire confidence.

Try to get an i5-4440 on there, that's really where the rubber meets the road for performance in all sorts of games.

i just game on it though like 4-8 hours a day (Crysis 3, Da inquisition, BF4, Farcry 3 and 4), no problems so far. i did a 5 mins prime 95 with it and it looks good also used valley and firemark benchmarks. so far so good.

also read that you can oc a g3258 to 4.4ghz with this board with no problems encountered.

There are lots of builds running raidmax PSU's and no reported problems either. Does one report of success with garbage power regulation mean that the entire PC building community should change it's philosophy on the importance of quality power regulation?

Just an FYI, power regulation doesn't end at the PSU, in fact, the 2nd highest current power regulation system in most gaming computers is the motherboards CPU-VRM's.
