i have the dfi board you're planning to get
using the 66.93 stock driver, i get 45k @ x2 and 53k @ x16, so if that xtra 8000 points matters to you (and you're planning to get another video card), you should think about getting the SLI version of your mobo (unless it's over your budget)
also, does anyone think the TT case's psu is a lil bit low? 18A@12V (but i'm pretty sure it'll work, but if you plan on overclocking i don't think that psu will do it)
