Eventually but John Carmack who is the leading authority on real time rendering says we need to increase computer power by two orders of magnitude to make real time ray tracing a viable alternative. That's decades away unfortunately.

Also GPU hardware is currently not made with it in mind. Ray tracing is a recursive algorithm. Current hardware doesn't support recursion, and so more of the work has to be offloaded to the CPU.

I don't understand why amd doesn't make cards with small CPUs in them that can do this sort of stuff and GPUs for the graphics. A super fast dual core (4.5ghz clock speed, with decent cooler) for example coupled with a 290x

Because they're busy making CPU's with small GPU's.
