Will my CPU bottleneck a Radeon 6950 2 GB?

It's a pretty old microprocessor, so it might.

I wouldn't be so sure about a "bottleneck" but it wouldn't push the 6950 quite as well as a 2500 SB CPU but i don't think it'll bottleneck it. Best bet is to see if you can push the clock sped to 3.0 or higher.

I have a Q9650 @ 3.6 pushing a GTX 460 1GB and rocking Skyrim at ultra settings with 4XAA and 16XAF and i would not worry about a bottleneck if i was buying a GTX 560 Ti or a 6950 2GB.

what do you use the card for, games ? and what games at what res/monitor size....opsys.... and what makes you think you need to upgrade ? you may not see much of a difference for your money.
