If you are gonna get a power supply,go ALL THE WAY,get a Xion 1000W power supply (6 12V rails @ V1:20 V2:20 V3:20 V4:35 V5:35 V6:20" for about 100 dollars at TigerDirect. Now,I don't really know WHY everyone says intel is a better processor than AMD,you can get a processor with the same spec on everything as an Intel,but spend a whole heck of a lot less,Core i7 965:1000 dollars AMD Phenom II X4 955: about 320, they're about the same,and what isn't you can always overclock,I also believe that mobos ready for AMD processors are a little cheaper too
