7970 and Phenom ii x4 955 Bottleneck Question

Last response: in Graphics & Displays

Hey,

I am going to upgrade my 6970 for the 7970 3Gb but I was wondering if my Phenom ii 955 x4 @ 3.612ghz would cause bottleneck?

I have a mediocre mobo at the moment but I was wondering, gaming wise, if I would see a difference in frame rate if I upgraded my current CPU for the i5-3570k overclocked to 4.2ghz with a $70 mobo?

Can my Phenom handle all modern games?

Thank you

Well maybe it wont get bottlenecked ,however i'm using 660 ti on a 955 n there is no bottleneck and maybe it will , anyways i'd rcommend u buying the 7970 and see if its gonna be bottlenecked or no and if u found it was then try to save for a couple of months to buy a new CPU, Mombo and the cpu u'v listed is a good one i'm telling u so cuz i think u have 50% chances to run ur system without any bottlenecking with ur current system and upgrading to better GPU is better than upgrding to a cpu in terms of gaming !

Great, thats exactly what I'm going to get, thanks allot, and yeah I will be overclocking. :) 

Like Dennis said it is a good backbone and I can always upgrade my card later. Anyone know what I can do with my mobo and CPU? I don't think I can sell them as I accidentally threw away the boxes :( 

Thanks everyone.

With a pII 955, there will be high bottleneck with 7970. You will lose minimum 20fps in most of the games compare to 2nd/3rd gen i5. Even a 2nd/3rd gen i3 will give you more fps in games.

When you will use powerful gpu than 6950/7850 you need a powerful cpu/intel cpu to get rid of bottleneck.
