I’m trying to come up with a CAD workstation build around $1200. Here is a list of components I have put together. I would appreciate any advice I can get on the components (especially the video card). I'm also not sure if the memory is a good choice. It matches the motherboard "DDR3 1600" but the processor's memory controller says "DDR3-1333". Is this a problem?

This puts me at $1,272.86. Will these components play nice together? Is this a decent build or should I start over? I would prefer an Intel Quad core, but I'm trying to keep the cost in check.

Thanks,

instead of the 790, I'd get the AS Rock 870 Extreme 3 for $89.99. Its a solid performer, and does 8x/8x crossfire

The AS Rock 870 Extreme 3 looks very similar and its cheaper. I like it. Thanks!

slightly more expensive, but your getting a WAY better GPU.

EDIT: RAM is also better,
