Well I believe I've already explained the benefits of a quicker hdd, the reason for severe FPS dropping in raids, and also my recommendation for graphics for you. It's your choice to not listen though
I have completely ignored those benchmarks you posted btw as they mean absolutely nothing. Sure showing "fps" is all well and good, is it showing average? max? min? framerate at a specific frame? Minimum fps and average are the values you really need to consider (maximum too, but less so), they're the important ones.. And I guarantee you that a single 4870 will offer you the better visual experience than 4850CF, not to mention will drain less power than any CF or SLi configuration (there are some people who care about that)
