I want to switch my last Windows box(my gaming rig) to a mac pro, however running visualhub and aperature on my mac mini is killing me so i'd like to buy a new mac pro with the 8800gt card, move aperature and visualhub over to the new MP, and add another faster video card in another pcie slot for a bootcamp windowsxp/vista gaming partition. Can I put a second video card into the Mac for the Windows bootcamp partition? I'd end up having the stock 8800gt card in one slot and put my 8800gtx in another slot and upgrading it when the next big card hits the streets. is this Possible? Issues?
