Actually no because I already have a GTX480 in my rig and adding a second one for 2-way SLI will cost me roughly $270. Whereas buying a GTX 570 will cost me over $300 and I will have just one single GTX570.
Alright guys I will try GTX480 SLI with my TX 750 watt PSU. WIll post back with results. I dont plan to ever use furmark
