The R600 looks to be really good, but that is to be expected coming out 5 months after the 8800. Regarding that heating problem with nvidia, I don't know where Greg73654 is coming from, take a look at two competing cards from both companies, the X1950 pro and the 7900GT. No matter which manufacturer you look at the X1950 pro has a massive cooling solution 99% of the time its double slots, while the 7900GT has a puny heatsink and fan. The fact that ATi needs such an extravagant cooling solution shows that it generates more heat then the nvidia, my graphics core is 45 degree Celsius at idle and a maximum of 90 when underload, but that is due to me massively overclocking it and using stock cooling, I have changed to an aftermarket one now.
