We just loaded up SC2 in a old desktop = AMD (3.2 mhz dual core) , error ridden Vista, and an 8800Gt card , and it worked well. So, I doubt you will have any trouble with the 2 v-cards you mentioned, unless you have CPU or RAM trouble in the machine your planning to play on. Maybe you can start a new thread posting what the other parts of your setup you have or are planning to buy, so help can be more specific.
