I want to upgrade my graphics card but I'm not sure if I'll need to upgrade my cpu as well in order to get the most out of the graphics card. Any help will be greatly appreciated.

Unfortunately, it will bottleneck the GPU.

It sure would bottleneck a gtx970. Probably only let it run at 50% at best.


It isn't that bad.... Yes it will cause SOME bottlenecking but not that severe you might lose 10-15% performance in some games. Although it might be worse on CPU limited games. CPU limitations show up more on multi-GPU systems as you can see from the latest tomshardware FX-8370E review where the 295x2 got the best performance out of a 4790K especially in BF4.

For AM3+, I'd go with a FX8320 and 990fx mobo eg ASRock 990fx Extreme 4. I'd also put a Coolermaster Hyper 212 evo cpu cooler on it. And get 2 x 4gb 1866 1.5v cl9 ram

10-15% is still unacceptable for me. So looks like I'll be upgrading. Thanks all

If you want to get your card now, and the rest later, performance will not suffer horribly with a 965. OC it up a bit, Northbridge at least since that gives the most performance on that chip with the least heat/voltage penalty.

This let's you do one step at a time so you don't need gigantic wads of cash all in one shot.
I did one step at a time. Video card, (prior 7870), then psu/case, (from crappy original), then mobo to the current Sabertooth, putting my 975BE in it, since it fits in AM3+ sockets just fine, played that for 8 months or so, then 8350/R290x of the current build.

And never stopped playing at any time for longer than it took to drop the parts in. Had steady improvements all along the way.

*doing this kind of thing means having a clear end goal in mind, to keep all parts usable and compatible at every step.

Only 15% is completely incorrect.

As i7Baby said, the number of getting HALF the performance at times is closer as I've seen both Skyrim and Starcraft 2 get 45% better frame rates with a GTX680 when comparing the FX-8350 and i5-4670K.

There will be games that see little bottlenecking. It varies significantly between games but the estimate of no more than 15% at most is way off.

MOST games will see at least 20% loss likely.

Which one had the higher frames?

Skyrim and Starcraft 2 are fringe cases. Most games are likely to be well under 20%. Starcraft 2's game engine is horribly optimized the game is fun no doubt but the engine behind the game is pathetic. Skyrim is similar in this manner. But again this is a game by game issue and depends on what games jake_larkee plays.

Speaking from experience here.
The Phenom II 965 @4.0-4.2GHz will bottleneck anything over a 760. It can run the 760 with no bottleneck, but anything more it will.

Source: 965@ 4.2 GHz and a 760.

i have in 2011 phenom II x4 955 oc 4ghz + gtx580 & i update cpu too fx8350 stock 10-15fps + in all games with 580gtx, 970 = 2x580.
