2 x 7900GTs (overclocked)
4 x DVD Burners
Theoretically, this all SHOULD work....lol
It would even leave open 2 PCI-X 100mhz slots! (so you could get even more hdd's if you really wanted too..) The motherboard also supports up to 64gb of ram, but i didn't find any 4gb sticks of ram to stick in its 16 slots...
Oh, and i didn't get the Quadro FX because its slower than a reg 7900GT at things like games, quadro's are made for 3d rendering like 3dsmax and such (in fact, the difference between the two are largely just in the drivers), and if i got that system you better believe that its for games
