Gt 640 and i5 3470

I would say get an fx 6300 and a hd 7850. It will cost you almost the same but will be much much better at gaming (almost 2x better)....

That combination sucks for gaming, really it does. Looks like you are planning on building a sub 500 dollar gaming PC. If that is the case, then you should just go for this build below. It is much better for gaming, and for gaming you do not need so much CPU power. Spending more on a GPU would give much better performance. So just blindly go for this build. If you have extra budget then please do tell me, then there would be some more room for improvement. But i am supposing that you are going for a 500 dollar PC so for that price this would be the best bet for gaming.

If you think that the answer helped, then don't forget to select it as the best answer. It would be highly appreciated by me.

Buddy.....the 750k will bottleneck the hell out of the hd 7870 in most situations.........a 6300 and a hd 7850 will be a more balanced build....
(Don't get angry at me this time around....I only want to rectify some of the shortcomings and help the person get a better build.....:)....)

Hey, why would i be angry at you? No, i won't.

I don't think that the 750K would be bottlenecking the 7870 since the synthetic benchmarks from various sources (like CPUBoss, i know not the most relevant but somewhat useful site) suggests that the 750K is close to the i3 3220. So i think that this CPU should do just fine because the i3 does not bottleneck the 7870. It runs just fine so i think that this CPU should also run just fine. And for the future.

Also the CPUBoss shows that the 6300 and the 750K has almost similar single core performance, and since it is a quad core the multi threaded performance is just good enough for gaming, so I am pretty sure that this CPU would not create a bottleneck.

I think this is a good CPU for the price which is on par with the 4300 (Source : CPUBoss). I have researched quite a bit and it also shows that this CPU is very much overclockable so overclocking it would make the single threaded performance on par with the i3 3220, and maybe even better. Who knows?

All these things are enough for me to assure that this combinatin would work without problem. So i think it would be just fine.

Are you really sure that this would create a bottleneck. Since the 750K is using the same Piledriver architecture, i think it should do just fine with similar Single Core performance and better mutli threaded performance when compared to something like the i3. Don't be afraid, this should do just fine. I am sure that helps :)

You see the 750k is a good cpu....there is no doubt about that.....but these Athlons lack a very important thing that the fx CPUs have.....And that this L3 Cache. And that can seriously hamper gaming performance in some CPU intensive games like starcraft 2......

EDIT: And here is a small piece of advice......Never ever believe in sites like cpuboss, gpuboss and hwcompare.....These are one of the worst cpu sites on the planet..

The Athlon is basically an A10 with graphics turned off and since the A10 is equivalent to i3 3220. I am sure that this won't bottleneck the 7870. Even if it does, then the amount of bottleneck would be very small and hence the performance would be much better than something like the 6300 + 7850. I am sure that this analysis is correct. Because no benchmark sites are used for this. I have just heard everywhere by everyone that the AMD A10 is the AMD's i3 equivalent. So i think let him ho for this. I do not see a problem with it.

A10 is equal to i3 but that is in a heavily threaded scenario. In lightly threaded cases the i3 pulls of a huge lead....
Ad BTW 750k is clocked lower than the A10 ( though It can be OCed but the headroom of OC will be less than the A10)

Yeah, it is, but since almost every next gen game is certain to be multi threaded supported that is it would run better with more cores, so i think for the future the quad core should be good enough and hence not a bottleneck. This is what i think, i do not find it to be a bottleneck at all.

That is why I am recommending the fx 6300....(looks like you forgot what the original argument was about...:) )
