Hi Tinr, I cant say much for the 5700 good or bad..never messed with one
I agree with Kudane on the 6800 tho that seems to be a great card and thats a good price too!!!
Look at
www.tomshardware.com they do alot of good benchmarkin. Thats where I decided on the Ati card over the Nvidia..I can actually use the AA and antiso that I couldn't ever touch with my Nvidia cards.. of course the fx 5200 was the newest I had. With the Ati 9800 pro 256 I can turn um up a bit and have virtualy no stairsteppin on IL2 sturmovik while looking at the planes...and other games like EQ run great!! I'm not really bashin Nvidia cards just the 5200 fx... it didnt even have a onboard fan.. kinda thought that was funny for a "new" card!
Anyway good luck its always a chore to shell out the clams on hardware since there is so many choises... just be glad ya dont got a Apple.. haha or maybe ya do! *opens up can of worms* "quick wheres the lid!!!"
