multi-gpu Multi-GPU, AMD + Nvidia?

[DJLinx]

Hello everyone, I'm new to this forum and the gaming side of things. I'm a computer science (programmer) major and thought I should start my way into the hardware side of things and basically learn my way up to increase my knowledge. So I started off on my curious and slow pasted journey to create my own gaming rig. This build is not quite finished, I am hoping to get a insight on some things before I further my conquest. 

----------------------------------------------

Build: ~~PC Hound *link to pc build (specs)*~~

Spoiler

Specs:

 

CPU: i7-6850k (acquired) 

Motherboard: Asus Rog Rampage V Edition 10 (acquired) 

GPU: RX 580 (acquired)

*I plan to have 2x RX 580s in CFX and a standalone Nvidia 1080 ti, I do alot of programming and rendering (whether it be video editing, photoshop, or 3D Modeling).*

RAM: HyperX Predator DDR4 RGB 32GB Kit 3200MHz CL16 (2 x 16GB) *On PCHound the specific ram wasn't listed, this is the true spec of ram.*

Cooler: NZXT Kraken x62

Power Supply: EVGA Supernova 1000 G2

Storage: WD 1TB SN750 NVMe, Samsung 2TB 860 EVO SSD, & WD 6TB Black HDD

Case: NZXT H700i (acquired) *This case should be compatible w/ the motherboard, not sure why I get incompatible reports...*

----------------------------------------------

I would like to know if having AMD & Nvidia graphics cards on the same motherboard is possible and how to make it work if it does. Also if having more ram exceeding the cpus recommendations will bottleneck my system in anyway (the motherboard supports 3333+mhz and up to 8 ram slots), but the cpu supports only 2400mhz and only 4 slots. *why make a motherboard specificly for the x99 chipset with these specs if the cpu can't handle it?*

 

What other accessories do I need and what should I understand? If you have any suggestions on what I need to do or if I need to make any corrections. Please don't hesitate to tell me... As I said before I am a complete noob to building a pc, but from the research I have done the is a great rig and it should be future proofed for awhile?! 

 

Not related to the issue, but if you'd also like to give me pointers on how to set up this build software and hardware wise, I'll gladly take advice from you and whatever sources, vid or articles, you could provide! 

Thanks you!

yes it works. stick an nvidia card together with an amd card is fine, your computer wont explode. they just dont like to doing anything related to sli or crossfire tho.

more ram is always better than less ram. motherboard is just a carrier for you components, the memory controller is on the cpu. when your cpu says no, its no.
