System 2 is only slightly ($15) more expensive then system 1... With the AMD system I can afford a much faster video card, but with the Intel system I get a faster platform overall and it's easy to upgrade video cards later.... although the PSU is also cheaper but I figure with Intel systems lower power consumption I don't need more then 500W (I also have NO plans for SLI/crossfire) I'm leaning towards system 2 right now but I'm wondering what everyone here thinks...

Use: gaming (720p or 1080p monitor)
