Honestly, price will probobly decide which gpu I end up going with... I might just wait for the 4890 to knock down the 4870's price a bit, mayhaps? Or an nvidia price drop?
Blah, in any case, those are the cards im looking at to run L4D, FEAR 2, Crysis, DOW 2, Grid, etc on my 24" Sammy @ those rez's, right?
