What would your budget be for this rig/upgrade? At this point if you feel you need to have it right now a 2500K will do the job aplomb and you can upgrade to a Ivy bridge when they come out which really won't be that long away. If you can wait the ivy bridge CPUs will be the upgrade path for the sandy bridge CPUs and like Danthrax said it will drive the prices down on the SBs. The 600 series Geforces will begin to trickle out here a preliminary roadmap
