There's no doubt that going to a faster cpu with a Radeon 9700 is always better because I don't believe there are cpus now that make the the 9700 your limitation.
As that is the case, every cpu available is "cpu limited", just to varying degrees.
There's a threshhold of cpu power you have to cross where it makes it more advantageous to own one card than another. For example, in the review I posted a link to they state the difference between the 4600 and the 9700 doesn't become tangible until you have a 1500+ Athlon.
As he has a 8500, which is much slower than a 4600, his gains would definitely be noticeable on a 9700.
Beyond that, if he upgrades his cpu sometime soon, he'll be set with his 9700. I just wanted to accurately answer his original question.
