Mass Effect chewed up and spat out one of my 1 gb RAM memory sticks so yeah cool game.
Yeah it will do that. Though really 2GB is pretty much minimum for any game made after 2006.
DD2 is pretty cheap right now, I recommend upgrading. If you live in the states you can get 2x 1GB sticks of DDR2 800 for <$100. Look for OCZ, Crucial Ballistix, G.Skill or Corsair.
Crucial Ballistix $30 after Mail-in rebate:
