But if it doesnt work well (ie ghosting) what a waste of money, hopefully your parents are understanding...but i know what your saying ..my dad would not let me return something, but my mom wouldnt care.....
2x1gb will get u dual channel, whereas 4x512 wont.....thats the main difference. but its expensive goin the 2x1gb route. I personally am fine playin BF2 with my 1gb and will wait a while before going to 2gbs. I just shut down everything before I play.
