I keep reading these posts about you'll be CPU limited if its under 3ghz for the 6800s, so I ended up buying my 9800Pro finally. I've got a P4 2.4ghz C, and was wondering, how much of a bottleneck would it be for a 6800? And it wouldnt bottleneck the 9800Pro right? If it does bottleneck the 6800, but not the 9800Pro, how much of a performance difference would there be between the two, generally speaking?
