Which is the best performing X48? is there going to be much of a difference between a DDR2 and a DDR3 board? the board i was considering is the ASUS Rampage Formula, http://www.asus.com/products.aspx?l1...70&modelmenu=1 , but it uses DDR2 which is my only concern. Is it worth going for a DDR3 board and 4gb of ddr3 1800 or going for the rampage formula with 8gb of ddr2 1066 for around the same price? this is going to be a 4870 crossfire system and will be built soon, though i am willing to wait if there is something great coming soon in a couple of weeks, otherwise just current parts.
