I had a 7600GT back in the day, I ran it at 800mhz core and 1650mhz memory and hit 4800 in 3dmark at 75c with a low wattage tec and FS-V7
Then I got a 8600GT, and the drivers were fail in every way possible.
I ~somehow~ managed to get it stable at 800/2000
But just look at the temps, with the SAME tec plate as the 7600 and a VF900-CU this time.
The gain? 400 points in 3dmark, now that' with 260mhz overclock on the core and 600mhz on the memory... somehow this card get's 200 points for 57mhz overclock so ...
I got so sick of this dang message
I bought this, so far it's great, decided to go corssfire once I sell that 8600GT when it get's back from RMA after killing my motherboard and memory.
