I'm replacing my AMD 1090T and with Black Friday approaching, we will all be inundated with component "deals" from one retailer or another. I've been delaying a X99 upgrade for 6 months and have decided to pull the trigger by Black Friday. I want to increase my CPU crunching power run VM, while being able to play games on this rig. I hope to run it 24/7 so a quality motherboard is a must. I've been out of the loop on component/upgrades and can use some help. Any and ALL recommendations are appreciated.

I plan to save money and use some of my current components.

Here is what I have so far;

Swifteck H240-x http://www.swiftech.com/H240-X.aspx
Azza Hurrican 2000 Case http://www.newegg.com/Product/Produc...82E16811517010
EVGA 120-G2 1300w PSU http://www.newegg.com/Product/Produc...-011-_-Product
2 R9 280x GPU http://www.newegg.com/Product/Produc...-678-_-Product
SSD http://www.newegg.com/Product/Produc...82E16820148443
HDD http://www.newegg.com/Product/Produc...-792-_-Product
My monitor is NOT 4k. I won't upgrade till it dies.

I need some recommendations on a motherboard I've been looking at the Asus Sabertooth 3.1, the Asus Pro\3.1 and a couple of MSI boards below.

The CPU for consideration there are only two. The 5960x and the 5930K
Micro Center has the 5960x for $899.00+ tax and the 5930K for $529 +tax which still beats Newegg pricing. Spend the $370.00 premium for the 2 extra cores or put my money somewhere else like a single gpu upgrade or one of the newer SSD

Memory 32gb or 64gb? My guess is if I went with the 5930k 32gb for crunching would be enough. Would I need 64gb on the 8 core? This is the memory I'm looking into.

I keep going back and forth on the 6 core or 8 core cpu?
Get the six core and the newer ssd or use my old ssd and go balls out on the 8 core.
Get the six core and upgrade my GPU?
Asus mb or MSI mb?
64gb ram or just buy the fastest 32gb for the mb?

I think that covers it all. Money is not a big concern just putting together the best practical machine.
Can I say practical when talking about spending money like this?
