I'm starting to plan a build for later this year and so far I know that I want two intel 750 ssd's in raid 0, a 4tb mushkin ssd (when they launch later this year), 128 gb corsair dominator platinum (64 gb will be a dedicated ramdisk for tracking if faster than the 750s), and a r9 390 for a little gaming @ 1080 or quadHD. I'm torn between a 12 core xeon which I can get for about 300 used on ebay or a six core 5820k which is about 400 new. Is the performance boost from more slower cores that noticeable in audio production?
