Lets see, hmmm ...
Well, the 7950GT has double the memory, and there are MANY gaming scenarios (though by no means all) wherein >256MB of memory will get used, thus automatically making the 256MB card 'choppy' compared to a card with extra vram beyond what is being used.
The 7950GT has 20% more pixel shader power (20 vs 24), and about 15% more vertex shader power (7 vs 8).
And the 7950GT overclocks at least 30% (475 vs 615) higher on both core and vram. And on that generation of card, that 30% ALONE means damn near 30% increase in performance.
Factoring in each of the above: memory amounts, pipeline differences, and clock speed differences, I'd say on average you're gonna lose on average about 40% of your performance. Where you used to get 50FPS, you'll get 30FPS. Roughly.
I'd say it's about the difference between a 8800GTS320 and a 9800GTX.Edited by brettjv - 6/6/08 at 2:30pm
