I have just upgraded a graphic card on one of my system from ATI3870 to NVIDIA GTX295. NVIDIA and ATI don't work along well so I'm taking ATI3870 off and have it back in the book. I'm currently crunching MW@H on another machine with ATI4870. Wondering if there is any good to add that 3870 card into this system? I've heard that we cannot crossfire 4870 with 3870 but will it help 4870 crunchs MW@H?

It should Crossfire-X, though both would run at 3870 quality (at least for gaming). For crunching, it's an unknown factor. Give it a go? =P

No, you cannot Crossfire a 38xx and a 48xx card together.
