6870 or gtx 560
TYVM for your info regarding replacing my 2 ATI Radeon 4850's. As you can tell, this is not my forte, but I am comfortable with changing video cards as the ATI's always required removing and dusting almost monthly. I've decided to go with the EVGA GeForce GTX 560 Ti DS Superclocked, it seems to be a good fit with my equipment. From what I am reading, it seems to run cooler than the ATI. That was the problem with my 2 cards, always getting hot even tho the case they are in is the Cooler Master with fans everywhere.
