lets start by you telling us what your current graphics card is as well as your other computer specs. you can get this info by going to start>programs>accessories>system tools>computer. if your computer doesn't currently have a graphics card in it capable of playing SC2 then chances are the rest of your computer may have some problems as well. also, blizz has always been very good about having very low demand settings for their games so I wouldn't worry too much. You'd probably be able to play it with a 128 mb graphics card on low settings. 512 would be the max I would guess. btw, you've got time on SC2, its not supposed to be out till December if i remember correctly.
