While I agree with most of your points, a bunch of extra graphics cards won't really be helpful for ray tracing because of the amount of recursion required. It can be done iteratively with some modifications so it would actually run on GPU hardware, but the overhead in doing this is greater than the performance boost parallelism grants the user.
Besides, ray tracing pretty much sucks compared to modern rasterization techniques until you add in radiosity, caustics, distribution, and other extensions. And if all that's added in, I don't care if you have 12 cores, it will not run in real time.
