The 4850 X2 is out?! O_O
For 430 bucks, it seems very well worth it, keeping up with the 500 dollar counterpart, the GTX 280. According to that review the only problems were that it was a bit loud, and that there's driver issues. Both of these can potentially be fixed in a few weeks. And if the price is supposed to be even lower, then I think that card will be an amazing value.
