if you're not going to go SLI then just get a regular board w/o the SLI, imo sli is pretty useless since one card is already enough
second, i'd look into a seagate HDD instead b/.c they are quieter...dunno what you want
third, i dunno how much those ram you got are, but upgrading to ~$185 ocz el platinum Rev2's will give you a very nice OC
lastly, if you plan to upgrade in the future but use this computer,then i suggest you get an OCZ powerstream (520/600) instead
