Ok its ALMOST official. 24 pipes for the RS520, same as the Nvidia card. It will be clocked a little higher though. It all depends on the price ATI is going to put it out now. So all you people that are waiting, the Nvidia 7800GTX looks to be a pretty good buy right now, considering that the RS520 will be almost the exact specs maybe clocked a little higher than the Nvidia card.
6600GT PCI-E for sale/Trade. Check the FS/FT forums on tech-forums for details.
