Didn't AMD buy ATI? Pretty sure they just call it AMD now.
I wouldn't do SLI/crossfire unless you are doing some crazy multi monitor hi res stuff, or maybe rendering where you need the power. Otherwise it seems people just do it to show how big there E-peen is.
I just go with the most basic MB, the less bells and whistles seems to mean less issues. Use the money you will save to buy better parts, or just save your money.
