it would run at 1/16 of the speed , if at all I believe it would work though they work in x4 and x8 slots but just with a high loss in performance. Why would you want to waste money on a card that doesn't work with your system anyway???
Thanks for the replies. I'm thinking about upgrading to a mobo with a x16 slot, how much work would that be? Just about the same as installing a new video card?
you need to unscrew the Mobo, Pull off the Heatsink, the CPU and HD's and stuff, but make sure you put you CPU and Heatsink first, then switch it out..
