here si what someone just posted in the 512mb gtx thread over at XS
"MWAVE is wrong on the clock speeds. I am certain. The retail box does not have the clock speeds marked on it. But coolbits will show them. One number is higher and one is lower....
BTW You buy these I hope you have a big PSU....in my test rig 256MB 7800 GTX SLI ran fine. With these...very unstable. My guess is a 550 Watt would be marginal. 600+ should be a must with multiple HD and lots of RAM.
The XFX card should MSRP atleast 100 buck less."
