I got one of these in the hope that can run either Xfire or SLI, seeing as it has 2 PCI-X slots but didn't mention either, so maybe it i both. Vain hope methinks.
Actually, I paid the £18 extra for this over the DS3 because of the SilentPipe and the Firewire... one ****-hot GPU is enough for me!
Trouble is, it don't work. Well, not with the G.skill DDR2-800 RAM i have.
