I'm wanting to dump it and get something new. and that 4870 is looking good.. I want it to be honest.. but I have an SLI board so I'm hesitant..!
Crossfire won't work on an Nvidia chipset motherboard, it must be an Intel chipset motherboard or an ATI chipset motherboard for Crossfire to work.
I own and use every day, the Radeon 3870X2 for gaming and so on.
If you want the 3870X2 or 4870X2 you must be willing to dump that Nvidia chipset motherboard. However a single 4850 or 4870 will work in your board.
