How bad will a Phenom II x55 bottleneck an Nvidia 680?

post #1 of 18
Thread Starter 
Hey quick question. I'm running a 3 year old system that I built... and to be honest it handles all the games @ 1080p at very acceptable frames, I havent really had a need to uprgrade, but now I want to upgrade my monitor to a 27" IPS @ 2560x1440 and I know I will have to upgrade my videocard if I plan to game at that resolution.

My question is regarding my CPU, Im wondering if a Phenom II (955 BE @ stock clocks) will bottleneck an Nvidia 680, if so, by how much? and most games being port-overs and not very CPU intensive, will I even feel a bottleneck?

The system specs:

AMD PII 955 BE stock clocks
Asus M479XTD EVO Deluxe
ATI (Gigabyte) 5850
4 GB G.skill
Antec 550W TruePower Modular

Thanks any savvy input would be greatly appreciated.

Best Regards,

Eli

Overall... depends on the game. If you use the higher in-game settings, you won't see much (if any) of a bottleneck due to your CPU. When running on lower settings or when playing a more CPU-intensive game you will have a bit of a bottleneck but it won't be anything too major, you'll still get good framerates.

In short, No it wont bottle neck it. I've got a mate that Ran Xfire 7970s on a 980 and he got great fps.

Depends on the game / application.

Are you unlocked/overclocked?

If you're just running dual (and non-OC) then yes there will be games where your CPU holds you back.

If its Quad-Core your ok if not maybe have some bottle neck in some games.... redface.gif

It will depend on the game, and even console ports can be very CPU intensive.

GTA IV is a console port and can use all four cores and needs a fast quad core to perform well; RAGE will use all four cores and will most likely bottleneck you, especially if you have the image post-processing option they introduced with the 1.2 Patch turned on.

Other games are still optimized for two cores, in which case you should overclock your CPU. Actually, you should overclock your CPU in any case.

Maybe just a tad! IMO it wouldn't warrant an upgrade though.

My question is...why would you put a card in a system that cost almost as much as the rest of the system? Why not put the money in a better CPU, power supply, cooling or even all of the above for the same price. PC's run at their best when they are balanced but it's your hard earned money and it's your choice. To the original question I ask this...why would you want to spend $500 to find out and if it does then what?
