I'm pretty familiar with the ATI GPUs and I've been reading a lot that they are a step up at the moment from Nvidia because of the higher end cards being able to support direct x11 as well as the price. In order to make sure I'm getting the best card for my money I want to try and become familiar with Nvidias cards. They are kinda confusing the way they label them. I'm trying to spend about what a 5770 costs- 150$-$170. Which Nvidia card is comparable to this? Direct 11x doesn't seem like a huge reason to go with one over the other. Or is it?
