PCIe X800 models already introduced (sales of which continue for the time being):
Radeon X800 XT PE (R423): 16 Pipes, 256 MB, 520 MHz Core, 1.2 GHz Memory
Radeon X800 XT (R423) : 16 Pipes, 256 MB, 500 MHz Core, 1 GHz Memory
Radeon X800 Pro (R423) : 12 Pipes, 256 MB, 475 MHz Core, 950 MHz Memory
Radeon X800 SE (R423) : 8 Pipes, 128/256 MB, 425 MHz Core, 800 MHz Memory
My mistake about the 8 pipes. Got it confused with a X800SE.
The X800 still will be slower than a X800pro however. The X800XL at 16 pipes and 1000MHz GDDR3 at 349.00 would be where my money is going. Offers 6800GT performance for about 30.00 less.
