The PCIe Dilemma

I'm a broadcaster who needs to use multiple PCIe devices and has run into lane bottlenecking in the past. I'm hoping to spend more (but hopefully not too much) to solve this issue.

 

I need to have:

- A 3080 Ti (at x16)

- A Magewell Quad HDMI (at x8)

- A Blackmagic Decklink Quad 2 (at x8)

 

I wouldn't mind:

- Extra PCIe x1 slot for random cards

 

From my research, I'm not getting there without a Threadripper. I don't want to break the bank, so using a not new model is preferred here.

 

But what I'm looking for is: Am I missing something? Is there a cheaper way to achieve what I want? Does my solution fit the problem?

 

Suggest what you can, always looking for new thoughts and takes!

Yeah, Threadripper is the only way to go, sadly. I want to run a GPU at X16, a 10GBE PCIE card, and a SAS/SATA controller card, but there's just not enough lanes.

 

I mean, you might be able to find a used Xeon workstation, but for that money, you might as well just go threadripper.

The low end threadripper has 64 lanes,The newest high end one is 128 lanes.

Unfortunately, the uptick in cost is extremely prohibitive.

 

Luckily, I'm not trying to do 3 full power graphics cards with a bunch of M2s or anything.

Do you think that my target for the 2970WX is alright?

 

Threadripper CPUs are no joke in price, so I want to make sure I'm not overspending... or underspending!

I don't see a problem with the 2970WX. I might actually look at a system just like that myself later, it comes down to it.
