I was looking for these to upgrade some workstations, and this was the best price I could find. The reviews say that this might not be an ideal card for a quiet machine though, as the fans always spin at minimum 50% - fixed setting on the card's bios. We've used these for speeding up image analysis and seen 100x speed up over the CPU bound version of the software. Can't say if they're great for games - but I'm sure someone else can comment! Heat?
