i think 7700 is like 5% worse, it’s slightly downclocked or running eco mode constantly, something like that, it’s actually reasonable get, but you should recheck reviews, cause i don’t remember very well what was the deal with them and if they can be clocked back to full, or nah. Depending how much work you do, could be annoying enough to skip it or fine.

yeah, dunno, 8gb kinda dodgy for modern games, but if you do like decade old stuff might work (+it will definitely get worse for newer titles over time, the consoles target like 12 gb internally)
