At the moment i have a 13700f and it looks like i have a cpu bottleneck with my current gpu (a 4090) and im not sure what would be the best option for upgrading since im also a bit flat on money now since i got my new gpu
Also im not sure if the prices here in my country are high but the 13900k is about 700 USD and the 14900k is about 800usd and the 14700k is about 500usd.
14700k if you don’t need to do work with software related stuff, 14900k if you just wanna do everything.
13th gen doesn’t have APO so forget about that.
Also 13700 is fine, no need for an upgrade at least for another 5-7 years.
Nothing should be bottlenecking generally either way unless you’re running a demanding game at 4k or doing some processor-heavy stuff.
