I went ahead and pulled the trigger on my new desktop. Final build:
Case EVGA DG 87
CPU: Intel I7 6800K
CPU cooler: Corsair hydro H115
MB: EVGA X99 Classified
Power: 1200W EVGA SuperNOVA platinum
Video Cards: MSI GTX 1080 Hybrid SeaHawk x 2 SLI with SLI bridge 4 slot model (couldn't wait for the EVGA cards anymore)
RAM: Corsair Dominator Platinum 32GB (4x8GB)
Hard Drive Samsung 850 Evo 2.5" 1TB
Monitor: Asus ROG PG348Q
Came out to just under $5,000 which was my target price tag. I wanted to thank you all again for your insight and recommendations - this is why I love these forums so much =)
Will update you all with pics after I throw everything together and get it up and running!
