definately the radeon 9800 pro-even though it has 128 compared to 256-no games today really take advantage of the extra ram. the arcitechture of the 9800 is far better than the 9600. The 9800 has a standard 8 texture pipe lines-better rendering- and has (most significant) 256-bit MEMORY interface-reduce bottlenecking and much better performance. i would say that the 9800 is about 30-40% faster than the 9600.
