Hi, I recently bought a new Dell computer. It has a AMD Phenom X4 Processor, 500gb HD, and a ATI HD Radeon 4350 Graphics Card. I hope to replace the GPU with a ATI HD Radeon 4670 so I can play games on higher settings. Can I crossfire the two cards for better performance? If so, how?
First of all you need 2 Pci-e x-16 slots on your motherboard, which is unlikely on a package comp. And even if it has 2 slots I wouldn't recommend using those two on a crossfire configuration. Also you'd need a chipset that includes crossfireX.
Most dells won't crossfire unless crossfire cards is one of the options when ordering. No point crossfireing such low-end cards anyway...the old 3870 has better performance than the 4670; a single 4890 wouldn't just blow away crossfire 4670's...it would desimate them.
