If you're into overclocking, the 9800 non-pro is about the same price and slightly better because the GPU overclocks very well.
But the 9700 PRO has better memeory for overclocking, and is a bit faster stock. Both cards are still strong.
Might want to wait a bit if you're not in a hurry tho, the new cards come out in a month or two and the prices may drop a little on older stuff.
