What is the best budget card for this rig that will allow me to crossfire easily in the future but still really cheap. I don't plan on spending half my gaming rig budget on a graphics card so let's say I would want to play games like skyrim or batman:AC on medium- high on three screens?
The GTX 660 Ti that is due in about 2-3 weeks is rumored to sell for around $250. It whomps the more expensive HD 7950 and can go toe to toe with the HD 7970 at times. I suggest you wait until that card is released and you can play Skyrim, BF on high settings over 3 monitors with that card alone.
