So I chose the CPU because it is powerful enough to support the games I wana play now and in the near future (Mass effect, Civ5, SC2, Diablo 3). Also this being AM3 socket I expect AMD to continue to support it for at least a few more years (hopefuly up to 10X CPU) so I can upgrade to a 8x or 12x core cpu in a few years.
I went this this motherboard because I like the 16GB max ran cap (some were only 8gb)
The 5770 seems like a good Mid-High range GPU.
Is the PSU enough? I plan to eventually run CrossFireX when I upgrade the video card to something better in the future and I will use my current GPU along with the new card. Do you see any compatibility issues with any of the stuff I mentioned? Thanks
