Well, I'm so amazed by these guys I bought two more for my old XP Athlon 2200 on Asrock K7 upgrade 600 mobos w/ 8x agp... there isnt much the Athlons can run anymore, Ibercivis is about the only thing that lets them play so they are turned off a lot. So what the hell, this keeps them from the recyclers for another year. $75 ea is a decent price for all new life - essentially a new computer that does pretty well. My other is making about 9K a day in Collatz and I'm hoping the new radeon (cypress) chips encourage more project coding for ATI.
