This is an old thread from 2020. Subsequent posts indicate OP ended up getting an Amd 6900xt with an Arc a770 for decoding. I have that same combination myself. When display performance is my paramount consideration, I get the smoothest most glassy visuals doing multicam cuts between cameras displayed simultaneously if my monitor is plugged into the Arc. Which I temporarily select as the main gpu in video prefs. But that's without any FX of any kind. After camera cuts are done, with only crossfades between clips, FX and grading comes into play. I then switch my monitor and main gpu back to the 6900xt and keep it that way through final renders because the performance doing everything is so much higher. The less parallel timeline seems much easier for the Amd to handle smoothly, even with heavy fx processing. At that point the Arc is relegated to decoding and Qsv rendering. I wonder if an Nvidia 4090 in place of my Amd might obviate my needing to switch gpus for multicam... but it's significantly more expensive, harder to fit into a case, throws off allot more heat, and requires a bigger power supply. The 3080 and newer Nvidias, btw, were tops in AI Torture Test results.

@Howard-Vigorita Outside of USA where prices are more flexible (if a card isn't selling prices goes down, possibly rebated by Nvidia/distributor/card manufacturer) you can buy a 4080 for about $US40 more than the upcoming 16GB 4070TiS's MSRP. 4080 may continue to fall. US seems to be a different market where prices stick close to MSRP or even go above. 4090 is expensive everywhere due to China ban and server racks of 4090's being used for AI.

There are many 4080's that are between 2.5 - 3 slot, some 4070ti's that are 2 slot. My 3080 is 2.5 slot, Problem is most 4070ti,4080,4090 are big in all dimensions.

@Former user I'm interested in this one at the moment. Relatively compact and the price isn't too bad. Likely because something newer is about to drop. I'll probably be retiring my old Xeon this summer and have to make some tough replacement choices.

6900xt and I have a 7800xt. Both are about equal I read. But you switch to another GPU arc A770 for decoding?Because my 14700K has a Integrated GPU for decoding. I have 2 monitors. I hope I made the right choice.

@BONLEV Yes, only because I got poorer hevc decoding performance from the 11900k/uhd750 using vp19 legacy-hevc decoding than from my 9900k/uhd630. The 14700k/uhd770 is a more efficient implementation. Vp21 now also has faster hevc decoding. Things should be way better. And the Arc should make a smaller performance difference unless they soup that up too... but the new model is not out yet.

Btw, here's a link to the: AI-FX benchmarks. Your setup would use the 7800xt for AI and media generation. I'm curious how it in fact compares to the 6900xt on those things. Not to mention compared to the 4090 which is the leader.
