memory problem.. help question

[geo8o2]

ok. i just bought this new dell. i think it's suppose to have 1gb of memory?

anyways i just bought this pc game, tom clancy's splinter cell. now it says i don't meet the requirements w/ memory. it says i have 958mb and i need 1000mb. aren't i suppose to have enough already? is there a way to tweak it so i can play? or do i have to upgrade? or should i complain to dell since i bought 1gb...

i really want to play this game!
