There are sometimes hardware compatibility problems with Windows Gaming PC where hardware drivers can make video editing slower, or unreliable.
I recently read on a blog post that Nvidia released a hardware driver software which caused Windows to not startup, and show a blackscreen.
Following a storm of error reports, Nvidia has pulled GeForce drivers v364.47 from general release. Malfunctions range from your basic stuttering to black screens, blue screens and crashes that leave you stuck in infinite boot loops. Rather ominously, the odd member on the GeForce forums has been requesting warranty advice. I'll wager that the Nvidia office resembles one of the nastier planes of hell around now.

I think, if you want one of the
best pre-built video editing computer, the Apple Mac Pro can be a good choice because it uses a Intel Xeon E5 with 12MB L3 cache and Turbo Boost up to 3.9GHz. The Intel Xeon Series of CPUs are used on very powerful web servers, supercomputers, and database servers, so it is fast enough for most video editing needs.
The Mac Pro also has two AMD FirePro D500 graphics processors with 3GB of GDDR5 VRAM each, so you also get 6GB of DDR5 RAM by having two video cards on the Mac Pro.
The Mac Pro can be upgraded to 64GB of 1866MHz DDR3 ECC memory if the 16GB of RAM is not enough.
The cooling system in the Mac Pro also seems pretty good at cooling itself without making a lot of noise.
But, the Mac Pro is
very expensive, so building a Gaming PC is more affordable.
