How badly would a new GPU bottleneck on my setup?

breakdown00 · Oct 7, 2017

So I built my pc probably 6-8 years ago. I cant remember but I have an i5-750, 8gb DDR3 and a GTX 760. If I were to go to say a 1060/70 how badly would it bottleneck? I know I need a totally new setup but to replace the CPU obviously I have to do mobo for sure and then ram eventually. Thanks for the input in advance.

It depends on the game. It's hard to say honestly. It will bottleneck, but I've not seen any benchmarks with a GTX 1060 or 1070 on a CPU that old to know.

If you are planning a larger upgrade later, then just go ahead. Still should boost performance over the GTX 760, and when you upgrade later you will get a decent increase in GPU performance too.

The GPU likely won't. Unless you are playing with very high detail + resolution, the the bottleneck would probably be on the CPU.

Though it depends on the games, graphical settings, resolution, and desired framerate as bottleneceking is only an issue if it' stopping you from your desired framerate.

Well it likely will bottleneck even without very high settings. Check any CPU review.

The difference in performance between the Pentium and any other CPU on the list shows the CPU is bottlenecking. That Pentium has two cores, Hyper-Threading, and it is close to a decade newer than his Core i5, so they are probably at best on the same level. That Pentium might even be faster.

IInuyasha74 :

I was saying the GPU would likely only bottleneck when under high settings, not the CPU.

GPU bottlenecking means the GPU is limiting the FPS and CPU not using it's potential.

I believe OP was mixed up between CPU bottlenecking and GPU bottlenecking.

Correct. I was confused between which would bottleneck. I actually never thought about it but I assumed the GPU wouldnt be able to get enough out of the rest of the hardware. Not the other way around. Interesting to know that though. Thanks for the responses though. To compound this question would it be worth it to go to a very cheap newer build from this current build to increase performance at a lower cost? Say maybe $500 for everything?
