I am trying to get my computer ready for all these games coming out now and in the future. I am not sure though how much performance I will gain from the few new components I would like to get. I am considering upgrading from a Phenom X3 720BE, to a Phenom X6 1090tBE. Also considering going from a 2x Evga GTX260 ssc sli setup, to one GTX570 (Which will be in sli in the future). Will this be a worth-while gain in performance for future multi-threading and gpu intensive games? I run 1920X1080 on 47" screen when playing games. Side note, I plan on building a little cube case for work gaming and using the old cpu and graphics will keep me from having to buy new parts for that.
