Dual CPU?

With the advent of GPU's, Is there any advantage any longer to having a dual CPU computer? Seems like a lot of expense if there really isn't a benefit.

Less of an advantage for applications needing less than 64GB memory, 6-8 threads, 40 PCIe lanes. There is an advantage for apps that need more than that: heavy AE, 3DS Max, Maya rendering, some financial and scientific apps, servers that need lots of I/O lanes and low response latencies.

Single CPU (Core i7): up to 32/64GB non-ECC RAM, 40 PCIe lanes. Dual Xeons: up to 512GB ECC RAM, 80 I/O lanes.

Depends on the processing being done and whether GPU can do it, or the process was written for GPU. I know in the transcode dailies world, both are still important. Color correction is done via GPU, but the actual transcode process from codec to codec is still CPU. Also, debayers such as RED, and most likely others do not use GPU.
