Actually the 6200 didn't really do too bad. I used it on both my old Athlon and my new E6300 Core duo.
It was the XFX brand that already had all the pipelines unlocked... AND had a slightly higher clock speed (I guess it was their 'turbo' version of sorts).
My 7900GS still beats the crud out of it though! I would still like something better, but I just can't justify the cost of an 8800 or 9800 right now...
