Hi, might be a stupid question but anyways: If I get a (say) 1GB 3870x2, would that mean that it would use up 1GB of main RAM for memory addressing? I have only 2GB in my budget Asrock 4Core VSTA mobo (and it doesn't take any more). Would this therefore compromise total system performance to the extent that opting for a single 512MB card is actually the more sensible option? Using Vista 64, with Core2 E4300 @ 2.4GHz.
Sorry for my ignorance
