I have changed my mind so freaking much I don't remember. I know I have looked at the 480, 6950, 6870, 670, 680, and 580. I was originally back in the day (january I think) I was going to go with 580 SLI, but I don't know now. I would think either a 6950 CF or 670 non SLI. Be about the same price either way. But again, I am on a limited resolution currently, and I am very picky so I don't know what I will do when I go to upgrade the monitor. Probably going to get a better case eventually too. I like the 912, but it is so small. eh, but that will be left for later.
okay, so i will stick to the 4870 and still be execellent for what I do. gaming my CPU is the limit right now anyway. I was getting 30FPS on MOH with FAH running and high 50s with FAH off. So a 2600k should help some. I know it will help with ArmaII as it recommends a i5 iirc.
