It's time for xfire since Metro 2033 won't run completely smooth maxed out (seems poorly optimized, nice graphics though). So, I need a 4890 Almost any good brand will do (so no xfx ). Thanks! EDIT: Mmmm, I guess I forgot to put a detail in here. I want used cards only. I'm not looking to stick a new card in my aging system even if it's only a little more in cost. It's just past the limit and what it's worth to me.
