This was more of a dream build, rather than an actual definite replacement. The E series intel chips are ridiculous...6 cores running with hyperthreading essentially making 12. The Hyper X SSd's are some of the fastest SSD's on the market, and throwing them in a Raid Array will boost performance pretty nicely.
The memory is probably the fastest stock memory on the market as well...the timing scheme is insanely fast. And the quad-channel kit will work flawlessly with the Z79 chipset.
I'm a huge fan of Cooler Master and I'm absolutely in love with their CM storm series products. So I went with a beautifully designed case, and a cooler master PSU

The Radeon graphics was more of a interest...I want to know how well the Radeon can outperform the same class graphics in the Nvidia series. I would normally the intel chip with an nvidia, but I've always been an AMD fan. I've just never built an insane AMD computer.
