GTX 680 With AMD Phenom x4 980 Bottleneck?

I have an AMD Phenom x4 980 @ 3.7 GHZ,

If i pair it up with a GTX 680 would there be a bottleneck?

If there is a bottleneck and I overlock the CPU to 4.3GHZ would this alleviate the bottleneck?

I think there would be a bottleneck. Overclocking would probably help but not completely solve it.

Do you think it would at least use 80 % of the GPU?

no bottleneck, no way.

I'm going to assume we're talking about games here, and there's no way to answer "would there be a bottleneck?" because every game is different. In games that use very little CPU, you could get 100% utilization 100% of the time, but in most games you'd be average less than 80%. Any titles that we need to specifically address?

Crysis 2, Skyrim, and MW3 for now

Little bit, massive, and none.

Im assuming that Skyrim is more CPU intensive? How massive would the difference be?

They aren't that far apart.

Regardless the higher your resolution the less you'll experience this "bottleneck". Just so you know. It also all depends on the game, and despite all that said a 680 wouldn't be a bad fit, however with the 7970 being a little bit less powerful and being a fair bit cheaper now that there was a pricecut, I believe that would be a much more fitting graphics card.

Also there is always overclocking potential.

If you give it a good overclock to 4.3ghz it should minimise a bottleneck, what graphics card are you currently using?

and no in game you wont see any difference as long as you have a quad core running at least 2.4ghz


Wow there really wasn't much difference when it came to frame rates :lol: 

But this was with a GTX 580. I guess if i overlock it, it would perform better!

why so worried about bottleneck..?

as long as it reach 60 fps, you'll not notice the difference..

future game is more gpu bound than cpu bound...

so dont worry, fasten your seatbelt, and ready to race...:D 

* the only part in rig that cause bottleneck, is mechanical harddrive...

Hi there. I can tell you that for 100% chance there wont be bottleneck! How can I be so sure? Well because I have a gtx 680 with a phenom ii 955 (oc to 3.8) and there's no bottleneck, my frames are almost the same than most benchmarks around. Good luck

Who cares? [:lutfij:4]

If it does hold you back a bit, it won't be much.

Here's a Sapphire Radeon HD 7970 3GB for $450 after $10 rebate

I wouldn't worry too much about your PhII at 3.7GHz holding that back too much, either.

Check out Ryan's OC Guide and post up any tweaking questions over at the AMD Over-Clocking forum. Upping your IMC/NB from stock 2000MHz to 2400MHz+ can add quite a few frames if yah need them . . .
