Looks good. I see the MoBo has support for IB when its released.
For the GPU's. What do you think of HD 6850
Big fan of lifetime warranties.
life time warranties are a joke. The reality is that no one is going to keep the product for life so it doesn't matter at all.
Here are some charts for BF3 GPU benchmarks

Now this is only for Nvidia, but I could not find one for ATI/AMD performance. If any one knows of a graph that would show ATI performance to contrast this with, I would appreciate it if you could post it here.
I have head a lot of people say that the 560 Ti is whats going to give you a enjoyable experience as compared to other cards. Now I am not a big ATI graphics card person so all I know on that side is that the same thing about the 560 ti is said about the 6950. I mean if I were in your shoes, I would bust my butt saving every last little penny on the other parts of your PC and spend a MAX of 250 of a GPU. I mean if I liked at the budget between your Mobo and your GPU, the total max budget is 350.

That in theory gives you 235 dollars for the GPU. The more you dump into your GPU, the better off you will be.
