Are you going to use multi-screen, what size screen(s), what is your current rig, what are you willing to pay for, and where are you buying from?

Well I have the MSI NGTX560-Ti Twin Frozr II 2GD5 and it's just the 2GB version of a regular MSI NGTX560-Ti Twin Frozr II. On TigerDirect, the GTX560Ti costs $250. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1318193&CatId=3669. I highly recommend the GTX560Ti Twin Frozr II, but there's also the thought of waiting until the 600 series comes out so the price goes down, or pay for whatever is $250 at the time.
