Ok great these are the responses i wanted, i have never went INTEL so i didnt really know what was going on too much. I really want to go with a 1000w PSU, if you can recommend a better 1000w then sure i will check it out but the reviews on this one are solid, from what i have read it helps with the SLI with the gtx 460s, and also from what i have read these two super-clocked 460s will outperform a single 580. I didnt know sandy bridge is dual channel, thanks for pointing that out! Hmmm would be nice to find 2 sticks of 4gb each , or should i just do 4 sticks of 2gb each ? Money isnt too much of a problem on this build but i don't wanna go over 2 grand.
