God... I'd feel pretty lame as well if the next-generation AM5 7900X produced such a massive leap in performance over the platform I just invested in not long ago. The 7900X can often be found to be priced for under $400 USD. Hell of a deal as a "jack of all trades" CPU - Great for gaming and everything else. The gaming benchmarks also show quite a substantial gain of the 5900X - AM5 cost more to "get in" but there are certainly advantages to this. Anyways there will always be people out there whom are just bitter that the platform they invested in ways simply left far behind - It's just how technology works - there will always be something superior just around the corner.

Have both the 5900x and 7900x now both running with 6900xt Radeon founders edition. To be honest, can't really tell the difference between the 2. Better single core performance for sure but at the cost of more power and heat to dissipate. If ya have a 5000 series I'd stick with it for the time is not worth replacing the mobo. Ram. Cooler at this point when the 5900x is still far from being a bottleneck.

For me 30% performance gain single core is not enough to spend a big dollar. I'll wait 4-5 years.

I totally agree! If it’s not 50 or above not worth it really and granted you have to switch everything including the motherboard due to AM5 (in my case).

Up to 40% more power consumption, for up to 40% speed (multi-core). Not really a game changer if your CPU wasn't a bottleneck before. Iβ€˜ll stick with my 5900x.
