I just "cranked up" my first GPU cruncher on PS3Grid. I picked up a $70 Nvidia (8800GS), and bolted it onto my AMD 9550 cruncher with some duct tape and paper clips. It seems to be werking so far, after a few dayz of cursing at Linux and trying to load drivers and apps, Holy Crud!!.

It should (might?) complete a wu by the time I get home this afternoon (fingers crossed!!).
