Question Bottleneck, need upgrade ?

[Modduss]

I recently upgraded to the Asus RTX 4070 Super from the 1660 Ti but the problem is that my CPU can't keep up with it. I have an Intel i5-9400 along with an Asus Rog Maximus XI mobo, and with the new market and so much scope for upgrades I dont know what to get since I'm going to need a new CPU and mobo.

Also, I'm not even getting the full potential out of my GPU since I'm on a PCIe gen 3 and i think its only x8 so I just need some advice on what's good. I don't have a preference on platform, but I have a decently limiting budget but not absurd.

I hope i gave all the information needed and I hope you guys can help, thanks!

8-thread 9700k isn't too far behind 16-thread 13700k at 1440p

I would check to see how close to those numbers you get with your 6-core 9400 before considering an upgrade. But somebody on eBay has a new 9700k up for $82.49 right now.
Many people suggest 6-core CPUs do fine with a 4070 but those are usually 12-threads, and only i9 in 9th gen has hyperthreading

the i7 is reasonably priced for 82. The other routes you can go on a budget would be a socket am4 ryzen setup or you could pick up an LGA 1700 series board that accepts ddr4 and go with an Intel 12600k or kf for not a lot of money and still be able to update to a 14th generation part.

If you have a little more money consider a socket am5 ryzen system but that would mean swapping to ddr5 as well adding a bit more expense.
