Installing ( 'dual boot' optional) and using Linux Mint V22 cinnamon is quite easy in most situations although I'll admit to not using dual boot in a couple years. Especially with Nvidia cards and using the Costamagnaianfranco/Boinc alternate source (PPA) for BOINC install.

I think it's Costamagnagianfranco/boinc
I added a "g" for gian and made the large 'B' in boinc a small letter, I don't know if the capital or small letter makes a difference but I do know that you DO need the 'g' in 'gian' to make it work
I have a 7900xtx on my bench, so I can run some tasks later as a sample.
The XTX in addition to the increased clock speed over the XT, also has more shaders, TMUs, L2 and a wider memory bus. It won't be a direct comparison, but my guess is the XTX is probably 15-20% faster than the XT on O3AS.
Your 7900xtx is running O3AS tasks in +/- 13min.
Are you running only 1 task at a time? or more concurrently?

7900xtx is running 3x tasks. Which would put it at roughly 3.4M ppd running 24/7.
Anything over 3x tasks would crash and reset the driver. I haven't had time to look into what was actually going on, so I just settled on running 3x tasks. Overall throughput might be bit higher at 4x or 5x, but I don't think it would have been all that much better than 3x. The GPU is running stock core/boost and memory clocks, with the power cap set at 460W. GPU runs Einstein O3AS tasks at 3025 MHz core, 2500 MHz memory, and average package power is ~315W, with peak power usage of 355W.

Unrelated, but somewhat interesting, is that I saw the same driver crashing issues when I was running BRP7 tasks on a 6900xt. It will run all day at 2x tasks, but falls apart at 3x. Meanwhile a Radeon VII will happily crunch 3x BRP7 and 6x O3AS. No idea if this is just a Linux/ROCm OpenCL issue, or if the same thing happens on Windows.

That is impressive, granted my system also downloads BRP7 tasks which are not as credit efficient as GW tasks but with the W7600 I get 900k RAC running GW tasks at 3x and the card is using 115 watts average, I thought the high performance cards are much less energy efficient than their low performance counterparts.
The 7900xtx could definitely be tuned to be more efficient. I just let it run for the last week to get a baseline of the stock performance.
When left alone RDNA2 GPUs will boost as high as they can, using the full available power budget. An undervolt + setting a lower max power cap would undoubtedly increase the efficency without losing much performance.

Looks great. I will also suggest testing with higher memory clock (2700 MHz?) and lower the core clock a bit for the same power envelope. IIRC in my VII testing, I set the core clock to around 1450MHz and memory clock around 1100 MHz, running 5 to 6 tasks per gpu.
I recently re-started my Windows/Ryzen 5700G system. And started experimenting with the "dinky" iGpu.
I am running the All-Sky GW application on it. The GPU load was running maybe 70% with 1 task. I have bumped it to two tasks which pretty much loads the GPU up. It looks like I will get a bump in the RAC for e@h with no issues.
However:
I am pretty sure that the CPU crunching is running slower now.
I believe I had the same results with Ryzen 2200G cpu's and certainly with the more elderly Intel iGpu's I have played with.
It probably has to do with using non-gpu ram on the gpus. (my understanding is that iGpu's share the regular MB ram rather than their own separate ram like a discreet GPU does.)
Just mumbling along.

The 7800xt or the 4070Super? Tey are about the same price here
