I finally cobbled together a PC to hold my Geforce 250. I have it clocked at 816/1250/1936, fan at 60%, temps holding at 69C. Am in a safe ballpark? It seems to cranking out the PPDs at good clip (787 at 6200 ppd). I haven't cranked up the motherboard yet. Will try when I get better cooling on the CPU. (BTW: I'm stoked so far).
