Could be great for us AMD owners, could be not.
I'm not a fanboy, I just hope it runs great on AMD and Nvidia!
Although you could have a good point on #2, since the Alpha had so many problems with Nvidia cards, but it did run flawlessly in AMD cards.
Since PAX is coming up in 2 weeks and they plan to have a bunch of GTX 580 SLI rigs there for the 12 v 12 competition, I wonder if Nvidia is making them a special driver just for that?
It's all about drivers
It'll run smooth on both Nvidia and AMD by the time Open Beta comes around.
