checked the case i'd be using & it'll take an ATX board (current MATX board in), so got a ASUS M5A99FX PRO R2.0 Mobo & 8Gb stick of Kingston for starters. Don't have much need for video performance, just for some graphic programs, music format conversions. probably just use the 1090T for some mild OC (yes, know water cooling is needed for some more aggressive OC'ings, just like to get the "feel" of OCing a system), then when the change jar fills back up a bit, more RAM , better CPU, etc, etc, etc ... (gad, when will it ever end???
