I am building a new pc and I have read several threads on graphics cards and other various specs and just needed some honest input. I have read about alot of problems with certain Graphics cards and need to make sure what I need to get and if its going to work for SL or not. The specs are as follows. Corsair Carbide Series 500r case 16gig of Corsair Vengeance DDR3 1600 Mhz (Installing another 16gig for a total of 32gig next month.) Corsair Professional Series HX850w PSU Corsair H80 High Performance Liquid CPU Cooler Asus M5A97 Motherboard AMD PhenomX4 965 Black Edition Deneb 3.4 Ghz Quad Core MSI Nvidia GTX 570 Twin Frozr III (Powered Edition) And I also have a 20+ Mbs ISP Connection My question is, would this be a stable enough system to run SL? Because I have read so many problems about nvidia cards crashing numerous times, that they get low fps, cannot view mesh, etc. Should I stick with what I have or go with Radeon or a lower quality card? My budget of course will not allow me to purchase anything of a higher caliber than a GTX570. Thanks in advance for your time and input.
