I got a guy who wants to build a sick gaming machine and plays Unreal Tournament He's got a Gateway GM5664, AMD Phenom Quad Core, 1TB HD, 3GB Ram... Specs Here He wants Dual 8800GTX cards in there. I told him his motherboard will not take dual cards, plus the 400W power supply would be insufficient. So he wants to salvage as much as he can and build a new machine. So my questions: 1. I need an AMD motherboard that will support Dual 8800GTX cards. Asus M3A32-MVP Deluxe - would that work? Seems like its got the dual PCI Express cards. 2. Power supply - how many watts would he need? 900W? 3. Cooling - what issues may I have with this configuration? 4. He's got an AGEIA PhysX Physics Accelerator Card, are these things any good? Never even heard of them until he said he had one. Im not too up on this extreme gaming technology. Any suggestions would be appreciated.
