Good spot. Jay's only testing 1440p/high rather than 1440p/ultra but hopefully that does indicate that Igor might have a dud. Will keep mine in the box for a few days just to be sure, hopefully a few others will bench similar combinations@PaulM
Just flicked through JayZTwoCents and he/they tested both the 5900X and 5950X with the MSI 3090 Gaming X Trio. Both CPUs matched or outperformed the 10900K. And SotTR was in their list at 1080 and 1440p.
Dude, Igor has a duff CPU.
