LGA775 still has a few years left in it. CPUs are no longer as important as they used to be. A recent LGA775 CPU isn't going to bottleneck upcoming graphics cards, and maybe by 2011 Windows 7, games, and applications will finally take advantage of multiple cores. On top of that, you have GPU computing/co-processing starting to take off; your GPU is going to give you an unprecedented boost in processing capability soon. Something like a Nehalem would largely go to waste in a desktop system that isn't doing rendering, scientific computation/simulations, or some other CPU-centric task. LGA775's main limit would be bandwidth, but I don't see that becoming a bottleneck for most people any time soon.
