Hello,
First I want to say I don't need help for a FULL build I just need to figure out the best CPU and motherboard combo for what we are doing... I might want some RAM recommendations too. And of course I am open to other suggestions. Also I want to know if there is anything wrong with the Idea's I putting foreword.
I need to build a new computer this week for our live stream setup. We are working on increasing the quality of stream and we need a new PC. I have been battling the question of what CPU to go with for quite some time(3-4 weeks). Our current rig using an i7 4770K on a Asus Maximus VI Hero. And our main issue is that it is running out of PCI lanes/bandwidth to run all the capture cards we have. I thought the best answer would be go AMD thread ripper... I have had issues with AMD in the past BUT I been hearing so many good things about them now... Also they are the only company supporting more PCI lanes which is what we NEED. HOWEVER the only Threadripper Motherboards I have found only has 4 PCI card slots. Which would work but makes upgrades harder... We only need 1 GPU and 2 capture cards for now... However in a few years we might need 1-2 more capture cards and another GPU to run other stage monitors with. That isnt including any extra Network or other expansion cards we might want/need. So I thought about going server board route... The AMD server chips have even more PCI lanes... However the issues with the boards is the I/O on the back we still need/want normal I/O but most of the server boards are super limited making us need the PCI card slots for more addon cards. Also this is a show critical PC and we want/need quick boot/reboot times and server boards are not quick.
So now I am thinking of looking back at Intel CPU's and boards... But non of their CPU's have "enough" PCI lanes as I would like to have without spending time validating our use case with the hardware. However I am open and considering Intel CPU and Boards. I would like to hear any recommendations on what you think I should look at or what is known good. I am most leaning towards using a Threadripper 3960X with the GIGABYTE TRX40 AORUS XTREME OR ASRock TRX40 CREATOR. My issues is that I have had bad experiences with these companies in the past but trust Gigabyte more and Asus the most. Also the reviews for the boards are few and less then 4.5 stars for ones I like.
Things I need:
- Support for at least 128Gb of ram
- Quad channel ram support
- 10G network (dual 10G would be nice but 10G+1G would be fine)
- minimum of 4 PCI express x16 slots
- 2x M.2 slots (or more)
- 6x USB 3.0 or faster ports in the back and 2x more USB 2 or higher for keyboard mouse
- Need support for at least 33 PCI Gen3 lanes for CPU and at most we need 44 Lanes Gen3 as far as I can guess
Budget (including currency): $4,000-$7,000 USD
Country: USA
Games, programs or workloads that it will be used for: Capturing multiple 4k camera inputs (6-12) and live mixing them in real time to stream out to the internet. Also running multiple monitors (2-5), potentially stage wall screens (unknown).
Other details: Most monitors will be 1080, 1440, or 4k most likely 1x4k and 2x 1440p monitors
Capture Cards we are looking at or might use:
Decklink Quad HDMI Recorder - PCI Express 8 lane generation 3
Decklink 8k Pro - PCI Express 8 lane generation 3
Decklink 4k Extreme 12G - PCI Express 8 lane generation 2
Decklink Quad 2 - PCI Express 8 lane generation 2
DeckLink SDI Micro - M.2 PCI Express 1 lane generation 3, compatible with B and M key type 2260 and 2280.
GPU(s) for the system:
1-2x NVIDIA GEFORCE RTX 2080 Ti
Let me know if any further information would be best
