sounds cool. nice processor! i used gigabyte board as well. just 3.4ghz cpu. i liked intel chips better though... (not sure why other than it's intel)

both gpu's on one board? havent done 2 gpu's yet. thinking i remember you need dual gpu board to fit two gpu's?  makes me wonder how you hook up 5 gpu's?

was reading some articles i found looking at these: https://www.google.com/search?hl=en&q=extreme+bitcoin+mining&bav=on.2,or.r_qf.&bvm=bv.45175338,d.dmQ&biw=1440&bih=682&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=9pJpUdqiJaLB0gGawYD4Aw
