because I cant afford it. If I pay for a step up... (245?, how much is one? I payed 360 for my card) then I sell it.. get 550-575 on here maybe) Then I only pay 320 for my dual 3870's, and then I have a better set up than I have now.. for only 50 bucks or so. depending on how much the step up is. hmm, maybe it is too much trouble..
