Anything of the RTX series is good, the more powerful the better. I'm having good luck with my Radeon VII, but those cards are ridiculously expensive these days. The newer Radeon cards (i.e. 5700XT) are good too. However, RTX 2080Ti seems to be at the top of our benchmarks, at least in Vegas 17.

@LongTallTexan - Demands: Do you do any heavy-lifting, demanding FX-ing? I can run Particle Illusion+MOCHA Pro+ MBL LOOKS and that's SMOOTH at Preview Mode.

Here's my rig: PC 10 64-bit 64gb * Intel® Core™i9 - 3.3GHz * 40Gb NVIDIA  GeForce RTX 2070

I would be wary of external graphics cards- isn't real-world performance limited by latency and other bottlenecks? I'd read reviews carefully to see what kind of performance benefits actually accrue in applications like video editors before upgrading your already reasonably modern GPU. Vegas still isn't the best optimized program out there for GPU support (so it might be a waste of money).

I don't know how it affects VEGAS, but in my video projection mapping software, Resolume, using external GPUs guarantees about a 20-30% reduction in the total power that the card would have if installed internally. Bandwidth is there, latency may not be.

Mmmmm...

I'm not really sure frOsty. I bought an Msi RTX 2080 ti because i found a cheap one on the internet.

But.. I put back my old Sapphire Nitro vega64 the next day.

Better acceleration for the playback, faster rendering in XDCAM EX.

So..

@Leonce-Barbezieux What kind of external enclosure are you using with these graphics cards? The 2080 really should be faster. Benchmark.

Sorry @RogerS I'm french and i don't understand what is an external enclosure...

And you know, with Vegas, a lot of things should be different...

We are beyond reality with this soft... Ahahahah.

But love it anyway. :)

Hi Leonce, we were discussing using different desktop graphics cards with a laptop. To do that you need some kind of external case that communicates with the laptop (generally via thunderbolt).

This is the one the original poster was considering: https://www.dell.com/en-us/shop/alienware-graphics-amplifier/apd/452-bcfe/gaming

I am getting the proprietary enclosure made for my system by Alienware called a graphics accelerator. Has 2 connections faster then a thunderbolt enclosure.

Well, it says there is 1 connection (I think you can put 2 GPUs in it, though), it uses a proprietary connection tech that apparently must be faster or lower latency than thunderbolt, but I'll believe it when I see it.
