GPUs Nvidia or AMD?

Not sure if this is the right section or it should be in the Post Processing part.

As it now appears that LR6 now supports GPU acceleration, and a new GPU is one of the last two things to do to the desktop, which GPU to consider is now becoming a question. As the GPU will be for LR work on stuff like panos, later a two monitor (one 1080 and ideally 4k) set up perhaps with a bit of gaming at 1080. The mother board will only do a single Nvidia, but can do cross-fire AMD.

What does LR prefer, Nvidia or AMD as currently considering either a AMD RX480 (8gb) once they come out or a second hand 980ti / GTX 1070 if the price drops a bit?

Now rocking the 4790k, with 32GB ram and OS and LR on SSDs, so it is only the GPU and NVME drive left to go in, current GPU is Nvidia GeForce 8600 GTS 512Mb.

Thanks Neil. Appears no advantage to cross-fire in LR. Looks like Nvidia is using OpenGL of 4.4 and 4.5 so above the minimum specs. And AMD RX480 is using OpenGL API (which I have not heard before) as the card is not out yet guess must be above the minimum specs also. I have never quite understood what the difference is between CUDA and OpenGL is, could not find mention of cuda so guess that LR may not make use of them?
 
Given cross fire is a broken mess a the best of times I would stay well clear.

A new 1070 will set you back little more than a second hand 980ti and it's faster, runs cooler etc
 
Prices of the new RX480 that have been suggested at computex say $199 so typically I'd say it'll be £200. For the horse power your getting it will only be 20-30% slower than the 1070 and at around half the price. It'll also handle all the games etc pretty well at 1080p given the card will sit somewhere between a GTX 970 and 980.

If your not bothering with dual cards and don't care for spending silly amounts then this really is going to be the card to get!

And I'm an nvidia fan boy through and through for the record.
 
Thanks Mark and Andrew, looks like the RX480 will be the one as the 1070 is too much money at the moment and 980ti while they have soften in price used still have a bit too go (guess there is a linkage here). A while back when last looking at GPU it was all about the CUDA cores now it seems that cuda matters less.

Cheers.
 
I wouldn't worry about cores, simply on the overall speed. A six cylinder car can outpace an older 8 cylinder car if you get me!

As for the 480 it looks to be a very sensible choice at that price point.
