i have a measly 2Ghz core 2 duo laptop and in september am finally buiding a pc,
Q6700
oz reaper 4Gb 800mhz
and 2 x 1Gb HD2900 GDDR4

support it at full speed x16 with a third ATI as physics?

found a DFI Lanparty but pci-e only runs at x8

would you not be better off just buying one gfx card as there are still not many games that support sli/crossfire and the ones that do dont give huge increase in performance

a single 2900xt 1gb or 8800gtx/ultra and a physics card would make more sense unless you are rich of course then go for 2
