Hang on, that star tech one is limited to 1200p/60Hz, so that wouldn't work, the second cable would though.
Personally I wouldn't touch AOC, but that's down to a really bad personal experience with them, their support or how they treat their customers when there's a problem.
Considering your hardware, I would go 1440p if you can afford it.
This is the one I had in Sweden for a few months, but I didn't pay that much for it.
This looks like a pretty good deal if you have the cash to spend.
Or you could go with something really curved...
There seems to be a bit of a shortage of screens on Amazon in the UK right and the only decently priced stuff is apparently Samsung.
