Used an A770 [non-1st party build, ASRock PG-8GB], in a Gen10 rig
Linux took it in, with relative comforts [0 mesa / audio chicanery]
My particular card seem stuck, to running fans at 100%, no matter whats going on shrugs
Regards to gaming performance-- I’d put it bouncing between a 2060 and 2070
While that kinda seems debbie-downer, when considering the power draws involved
I didn’t buy into, the perceived hype, of trading blows with RTX3070

Regards to game acceptance-- ended up a whole lot better, than I was fearing overtime
When all had been said, only one (1) game, seems to have vendetta [Starship Troopers]
The 8GB VRAM, has become a problematic point, through this year
Even if I did have a 1st party [aka 16GB], I’m sure the processing power be overwhelmed
[QHDUW, so yes I’ve been a bit mean]
For near future talk, on what happens after the A770
If Intel doesn’t offer a B7xx sku, for whatever [foolish] reasoning, I’ll shovel in an RX6800
The B580 has been, a well received GPU, for an understatement
Advantage(s) over your failing 6750, would be power sipper, more codecs and longer support
