im in kinda tight budget..i got a good offer for used phenon x4 965..im thinking bout choosing 7870xt as main gc..im wondering if this cpu will bottleneck 7870xt..n what is the best recommended gc for this cpu mto make sure it will not bottleneck..thanx~

if u oc 965 to 4.0 it will not bottlenect but below it there would be a bottleneck and to tell u 7870xt is a very powerfull card similar to gtx 760 so i would suggest u a 7870 ghz edition for best results if u dont want to overclock

I have a 965BE that's running at 3.8Ghz and I upgraded from a 6870 to a 7850 since it was a hand-me-down from another machine and I couldn't tell any difference in the games I play (Rift, Neverwinter, Planetside 2, Firefall) . . . Generally you would expect about a 15-25% increase with that change depending on the situation, but I couldn't reliably measure any change at all.

Though, if the graphics card is waiting around on frame data from the CPU anyway, you can crank things like AA and not have as much of an impact on frame rates, so if you can afford it I don't see any reason not to do something like this combination.

I'm using a Phenom x4 955BE @stock 3.2ghz with this GPU http://www.aria.co.uk/Products/Components/Open+Box+Comp... wihich is very similar to yours and have no problem with bottlenecking but i guess it depends on the resolution you are gaming at.
At higher resolution i believe bottlenecking is reduced due to the gpu having to work harder to produce the frames allowing a slower cpu to "keep up" .
At lower resolutions the GPU burns thorough frames quicker than the CPU can supply the data so you can get bottlenecking.
If I'm wrong I'm sure one of the experts will correct me.

The reason is that u upgrade to just 10% better car and that upgrade wont be easily noticable

Of course, that would be the case if what you said had any resemblance of the truth, but it doesn't so I guess it doesn't make much sense. For instance on Passmarks test ( http://www.videocardbenchmark.net/high_end_gpus.html ) the 7850 wins by 44%, over at the Anand bench charts (http://www.anandtech.com/bench/product/540?vs=549) the 7850 wins by around 19% in Crysis, 20% in Metro 2033, 38% in Dirt 3, 16% in Shogun, 21% in Arkam Asylum, 14% in BF3, 27% in SC2, 43% in Civ5 . . . Those kind of gains should be easily measurable with a few fraps runs.

The fact of the matter is that the processor is just so damn slow that the video card is generally just waiting around anyway, so the difference was not measure-able.

There is not a great difference mate

So pretty much exactly like I said, expected 15-25% depending on the situation, yet not measurable because the CPU is so slow. Thanks for clearing that up.

Yeah i think u should overclocking it to 4.3ghz

It won't make it, it's already a slow, hot, inefficient mess. I thought it would be great for the kids machine, but I should have got an ivy i3 instead, it would have been a much better value and a better rig overall. I guess that's what I get for trying to branch out and try AMD when I should know better.

I wud suggest u to go with haswell i3 when it is out
