Would my 965 BE bottleneck CF 6870's or a 6970?

post #1 of 4
Thread Starter 
I will either buy a 6970 or CF 6870's sometime soon but I am wondering if my CPU will cause a bottleneck. Do you think it would cause one?

I'm pretty bad at overclocking so I might not be able to go higher than my current speeds atm... My current voltage is set to auto. If I take auto off, anyone know a good starting voltage so I can start OCing?

Well my 965 is bottlenecking with my 580 with certain games so chances are that it will bottleneck with your setup.

It will definately bottleneck the dual 6870's, Phenoms dont scale too well with dual cards. However with a single 6970 bottlenecking should be at a minimal at around 4ghz. Should be on par with nahalem i7's clock for clock on a single card solution.

You should look through the forums to see what other people got their 965 to (check revisions too).

No. What you mean to say is at a high resolution you should notice no difference with a single card. Clock for clock the Nehalems are much faster and would definitely be noticed (by FRAPS) at lower resolutions.
