Are you saying that current 3080 owners are regretting their purchase? If so got any links to those posts? We have one questionable title with supposed vram issues (even though 3090 owners are reporting same FPS drops too but lets ignore that because of narrative...
I think the ones who got it for £650 are feeling very smug (I'm not ashamed to say I am
) unlike those who couldn't wait or couldn't get one and had to spend an "additional" £700 + just for 10-15% more performance.... Which will soon be superseded by a GPU costing £500 i.e. 4060/4070...
As shown by several sites, a 3080 is still regarded as the best GPU you can buy for performance to price, only beaten by a 3080ti and 3090 (if you aren't bringing cost into the equation)
Only people I can think of who should be regretting their purchase are the ones that couldn't get "any" GPU for MSRP as they're soon going to lose a fair bit of money.
