I am getting some nice numbers out the Quad when I can although I am now starting to find that 4Gb isn't enough some of these WU's are huge and eat up more than 1Gb of memory so I end up only using 3 cores or if i'm lucky 3 cores + my GPU which is slow but I can't replace it, I'm in save, save, save, save, save mode I need to get me moved to West coast USA..
