As I said in my last post why do you want such a high end board?

As far as memory goes decide which motherboard you are going to get first and then have a look at that boards ram compatibility chart at their site and see if you can get a decent deal on memory that is on the list. If not stick with normal DDR3 1333 or 1600 modules from Corsair, Crucial, Kingston, Mushkin etc. If you are not going to do serious overclocking there is no need for extreme memory. You will not see a performance difference between brands unless extreme overclocking, then its a crap shoot as to who is best. 4 Gigs of Corsair XMS3 1600 can be had for under $100 US.
