Back in 2016 I started a thread on another forum. We spec'ed out a editing machine build for Vegas and I built it. The build is listed below. I knew the software would take some time to catch up to the hardware. I'm now at a point where my GPU is maxed out and I need to find a new one or add a second one (if Vegas will utilize two).

My Specs:

- Windows 10 Ultimate running Vegas 20 Pro
- i7-6950x 3.0Ghrz 10 Core Processor Liquid Cooled HERE
- ASRock Fatality X99M Killer LGA2011-v3 mainboard w/ Intel X99 chipset HERE
- 1x MSI Radeon RX 480 GDDR5 8GB (2304 Stream Processor Units) HERE
- 64GB DDR4 2133 Memory
- LG IPS 4k 10-bit display model 31MU97
- Samsung 950 Pro 512GB M.2 Main Drive
- Samsung 850 Pro SSD 1TB capture scratch Drive
- Raid NAS (separate build)

Question:

Does anybody have a good suggestion for a GPU or pair of GPU's to purchase? I'm looking for something that's depreciated a bit, not necessarily top shelf but still has enough headroom to perform well with Vegas. I'm limited to something that will work with PCIe 3.0 per my build. The board also supports Nvida SLI & AMD Crossfire so two cards can be installed.

Notes on build:

The processor doesn't even break a sweat rendering. There's lots of headroom left there. However, the GPU is maxed out completely. So long as I stick to my main capture scratch drive for project there's not much issue loading up the clips... bit of buffering lag on some 4K clips captured in h.265 but other than that timeline playback at full quality is reasonably workable. Switching to file server incurs some lag, especially if anybody else is on network (typically not). I don't have a dedicated switch / line for the NAS, it shares bandwidth with other items on the line. Not explaining correctly but bandwidth is currently shared I'd like to create a dedicated 10Gbit line for the file server. The monitor was worth every single cent of $1000 I spent for it. It displays color accurate for print as well (something else I do too). I have an X-Rite calibration tool as well.

Build Philosophy:

I have a background in computer engineering and intimately aware that software lags behind hardware development. Many times hardware is designed that is never utilized in software. That said, it seldom pays to buy the top shelf components. I looked for slightly older hardware that had been or would eventually be supported in software. This saved me a bunch of money. I also originally bought a 6 core processor and recently upgraded to the 10 as they have become MUCH cheaper to buy second hand.

My original plan was to buy a second GPU but when original build was done, Vegas didn't even have GPU support when I did the original build. Now they do and I think I might be able to get a better GPU all together, possibly two if Vegas supports that.

Thanks!
