OK here is the questions. I currently have a GTX 560 Ti, i want to upgrade to the GTX 570. After looking around i am thinking that maybe 2x GTX 560 Ti will be a better option then a GTX 570. If i get the 570 i can add another within about 2 months from that. I mostly play BF3 and want to achieve ultra settings. So if you had the choice would you just get another 560 ti or get a 570 and SLI later on.
