That explains it. It was a bad time to buy both pcs and consoles and is probably the crux of the issue here. If you are talking MSRP, sure, but the PS5 was heavily inflated at that time too and sometimes still is. That's if you were lucky to be able to even buy the thing. If you did find it at MSRP, thats was an awesome deal because consoles also tend to be much more cost effective vs PCs at launch.
Even then I still can't find any console in my country for cheaper than a comparable PC, and the PC will last longer than a console generation. I put this and the fact I'll need a PC anyway when doing my cost analysis. I also factor in game cost, and PSN, and such. I just realized this might be different in the US, sorry.
You don't need a 2k GPU, period. A fraction of that will get you console level performance, and thats almost always more than enough. If you have $200 or less you can probably get something that supercedes my 2070 by quite a bit today and have a few bucks left over. And you can resell your old one for some money back.
But lets just rewind a bit, If a 960 can run TLOU and hogwarts legacy, a 1660 should very much still run any game you throw at it, even at reduced settings. What kind of problems do you have with games not running? Did a new, very heavy game came out that I'm not aware of?
Maybe its something you can fix and be able to use it frustration-free?
