Re: 4890 or the 4850x2
If it were me spending the money, I'd go with the 4850 X2. I've been looking at this card for my next build/upgrade, and if the price drops anytime soon, I'll be picking one up. I have not looked into the 4890 too much, but with them being the same price, if it can do just as well, or better in actual gaming, not just benchmarks, I'll gladly pick one up, as it is the newer card. Have you thought about Nvidia with the GTX275? It's comparable in benchmarks with the 4890, and the price is pretty much the same price, give or take a few dollars on which brand you pick up.
