I have the 6200, AGP form.. 256MB. I had to install a small fan onto the heatsink (did not come equipped with a fan) and it rarely goes above 85 degrees F.
I saw a HUGE increase in FR compared to my old 5200 card.. about 40%.. on my old XP2200 AMD system.
Now I have it installed in my E6300 system.. seems to be holding up well. I get a consistent 40-60FPS - 1280X1024 / 512texts... yes it may not be the best card out there, but it seems to hold up pretty good.
I found internet posts about unlocking all the pipelines on it.. and as I checked into the mods, I learned that they are already unlocked on mine... (XFX brand). I tried overclocking it a bit, but couldn't keep it stable above factory specs.
However, this may all be completely different on the PCI version.
Good luck
