Will a bad HDD bottleneck a GPU?

soldierguy97 · Aug 20, 2017

I have a GTX 1080 alongside a i5 7600k. I just recently had to wipe my really old boot drive because I couldnt get into windows. Before the wipe I saw a bottleneck on the gpu until I overclocked the cpu. Went from around 55% to 95% playing the same games. Now after I have wiped the drive im back to 55% with the cpu already overclocked. Ive got 16 gb of gskill ram oced before and after wipe, and my temps are perfectly fine on my cpu and gpu. CrystalDiskInfo has the old drive on caution so I idk whether to replace it or wait till it dies.

If it's going bad you should replace it anyway. It can't directly influence FPS in games but because of bad or nearly bad sectors may cause high disk usage affecting whole system. Now you still have a chance of cloning it and so not have to reinstall system and games. Once it dies completely, it's back to square one with everything.

Yep I have everything backed up on a second drive. Seems like it could be ok to wait until this one dies, but Idk. Oh and no bottleneck on Witcher 3, but that doesnt explain why went from no bottleneck playing something like GTA (which is cpu focused) to bottle neck with same settings.

It just might have to read more often in some applications than other plus there is always some action OS does on disk at all times like Virtual memory and swapping from RAM to disk and other way around. Whatever slows down system it mirrors at application(s) running.
