You know what'd be alot easier? A dual core cpu, one with a CPU and one with a GPU. So, you could have a 2.5GHz AMD 64 CPU, and a 2.5Ghz GPU. Then one half of the motherboard that needs the GPU could have it's own 2 ram slots, and the CPU one could have it's own 2 ram slots. They could have a mini liquid cooling thing and some fans.
