I built an i7 12700k, z690 motherboard, 32 GB ddr4 3200 cl 16 memory, Nvidia 3080ti 1 year ago. This week I had a new build done i7 13700k, z790, 32 GB ddr5 cl 36. There is a slight increase and I mean 10 percent max. It really feels like intel rereleased the same shit with minor upgrades.

Why build a new pc when you can already max out any game at any resolution?

I'm not sure how intel can keep getting away with this scam. These are the same CPU, released one year apart, with minor tweaks in core frequency, and a name change. But the issue is the 12900k launched for $200 more than the 13700k. So if you were the poor fool who bought the 12900k at launch, you got scammed out of 200 bucks.

Just save 150 dollars if you go for the i7 13700k, both have basically the same performance and if you do go 13700k you can upgrade to an i9 13900k later on and a 40 series nvidia gpu or a 7000 series amd gpu.

They’re both the same LGA1700 so you can always upgrade.

When they are released, the price point might be the same. Who knows? I'd rather buy an i5 13700k and get similar to slightly higher performance. That seems to be a wise idea unless I have to break my bank on a new motherboard.
