I have the 7900X. I originally planned on waiting for the 7900X3D but there was a sale on the 7900X for Christmas for $120 under MSRP, so I decided not to wait. I'm extremely happy with the 7900X performance. I upgraded to the 7900X from the i5-12600K and it made a pretty significant difference in gaming at 1440p. I'm glad I didn't wait. Yeah, the 7900X3D looks to be better than the 7900X, but not enough to justify waiting and paying extra for the X3D variant.

Are you saying that you bought a completely new platform: motherboard, RAM, CPU, etc - to move basically from a 1-year-old CPU, all that expense for a 1-year leap but not worth "paying extra for the X3D variant", ok.

Lilian, I did sort of the same thing and gave my 10-year boy my old PC. Ryzen 5 3600, 32gb ram, rtx 3080. Now I sport a Ryzen 9 7900x, RTX 4090, and 6400mhz 32gb ram. I mean the AM5 socket has a longer upgrade path than the LG1700 socket. At the end of the day, my boy flexing to build a PC is probably the most expensive time to build in our time. Flex my dude 😎.
