why didn't you just get a passive 4350 or 4550? stay with the card you have. you don't need any more shader performance.
several reasons like free shipping, great reviews, lifetime warranty, 1GB mem, not super-cheap and able to play HD video and game if I ever want to again, but now I'm thinking I should go for a FireGL V7700 since I use CS4 and I will be doing some AutoCAD and also so I can get an Apple Cinema Display
which only use mini displayport (so if I can just find a DP to mini DPadapter...damn sleazy Steve Jobs)
