Does a strong GPU require strong CPU

Solution


Technically speaking, no. Its the game you're playing that may (or not) demand a faster CPU, it doesn't actually have anything to do with the video card itself. The simplest way to look at it is that each game has its own workload for the GPU and CPU, and the one that struggles more with its workload will determine your actual performance. Some games really demand a fast processor, some demand so much from your video card that the processor barely even matters.

If you're upgrading from a really slow HD 6450, I think you will see some improvement even with a terrible CPU.

Not initially but to get the full performance of the new GPU yes you will eventually want to get a better CPU. Although it is not like it is required that the CPU and GPU be the same strength. Given how weak your current GPU is you are in a GPU limited situation now and you are talking about moving into a CPU limited situation so basically you would be switching your gaming issue moving to a better GPU.
