So i have an amd phenom II x4 925, 4gb of ddr2 corsair dominator and an Asus M4A785-M motherboard. i want to crossfire another 5830 but this motherboard only has one pci slot. Can someone please tell me a suitable motherboard that will use my ddr2 ram and my am3 processor while having two pci 2.0 x16 slots?
