Re: geforce 280 gtx sli debating about 480 sli...
I would agree that a CPU and motherboard and memory would be the first thing to do .The
i7-920 0r i7-930 scales better then the core2 Quad in SLI .I would upgrade to a i7-920 or
i7-930 and a new motherboard and DDR3 memory first and then get new video cards .
