I am about to build a new gaming rig and I feel like I've picked a configuration that offers some future proofing and a clear upgrade path. The rig I am building is a sandy bridge platform Z68 chipset so I can upgrade to Ivy down the road. Everything else in the build falls to preference and I think I've made the best choices for me. I was strongly considering the gtx 570 until I read that AMD might be releasing southern islands as soon as Sept. I didn't know the 28nm process was so far along so I feel like I'm in a pickle. I know the next gen of tech is always right around the corner and if you hold out for the newest thing you'll always be waiting but if I was to spend $320 right now on a gpu only to have a new line come out in a month I would feel burned. I'm honestly just looking for the community here to sway me one way or another. I have an ok gaming machine now but I just want to be able to upgrade by Oct. The only question I still have is can I use one of my old Nvidia cards as a dedicated physx card if a title comes out that I want to use hardware physx. I read that Nvidia made it impossible to do this anymore. Suggestions?
