Right now I'm still running the system on the left. It has served me well but I'm getting to the point where I am bored with it, and honestly tired of tri-sli. There is nothing mega wrong with it, little annoyances here and there. At the fore front of that is heat/noise/power. I loved the performance it gave but I really want to go back to one card. Question is, does any single 5xx series come close to 280 tri-sli? Or am I better off waiting for the next series in terms of comparable/better performance from a single card (not a dual gpu single card solution utilizing sli)? Does anyone have experience moving from tri-sli gtx280s to something newer?
