So the hubby isn't too keen on me leaving the PS3 on overnight. Something about fire hazard/electricity bill/credit crunch.
I'm going to install the PC client instead.
And Astro, that was complete gibberish to me lol, but just for future reference, the PS3 completed 1 WU in around 6 hours.
Edit: I went to install the cuda drivers and it said it's an older version than the drivers I have already, so I've left my drivers how they are and I'm using the Nvidia GPU client.
