I said "I think", which means I am not sure. Whatever the case, if you know better, please share with the rest of us, especially for the sake of the one who asked the original question. You are not being funny or witty, you just look like a moron with a post like that.

Now, Kaiser, about the video card; go with the 4850, since it and the 4770 are almost dead even. Also, you'll probably upgrade the whole system somewhere down the line, so the extra power is appreciated. It will only stumble if you crank the settings all the way up, and at that it should be pretty smooth in between stumbles, and having more RAM can reduce said stumbles.
