He shows a box of a rtx 3090... that is allUnless you compare both a 3080 and 3090 on the same/a similar rig it is not going to be comparable, his CPU is good enough for 1440p and 4k results but he seems to get higher score on 1080p than 1440p which it should not, some claim his RAM is holding it back.
He did at least provide pretty good proof he has the card.
