Anyways, I know my CPU is bottlenecking but I do know for sure my GPU isn't holding me back PERIOD. Although i am going keep this thread opne because there is some really interesting conversations going on in here
yes you're right your cpu is holding you back because the gpu isn't at full usage, i dont understand how you dont think a gpu bottleneck exists,
we're talking in terms of fps here, so which component is limiting the fps? if the gpu usage is at 100%, no matter WHAT you do with your cpu you will never get meaningful gains in fps, so the gpu will be holding things back, hence the gpu is bottlenecking....
you could lower the resolution, until eventually your cpu is the one that's stopping you getting more fps out of your system, but just because you have 200fps doesn't mean one isn't bottlenecking..... one will ALWAYS bottleneck the other (with different games, different engines, etc...)
say you have my 5850, now in bad company 2 i use 1920x1200 res, and high graphics and i get a dandy 80-100fps, now when i check my gpu usage, it's at 100%, so to get more fps i can either a) turn my graphics down(or resolution) or b) get a better graphics card... now if i were to change my cpu to say an i7 at 10ghz, my fps wouldn't increase beyond what is already set, because the graphics card can't do more than 100% workload....so with a 10ghz processor im still stuck at 80-100fps...
now we could lower the resolution/graphics settings to accomodate for this, and we would see an fps rise aslong as the cpu didn't hold it back at some point (let's assume 200fps)
so now we're stuck on 200fps, and the graphics usage isn't 100%...so to get more fps we HAVE to replace the cpu for an even faster one (or we can increase the graphics to get the same fps (200) and make the usage hit 100%,
the fact is most of us dont want to run stuff at lower than native resolution, or with a bit of AA when we're talking about high end graphics cards, so we assume you're on a SET resolution with graphics settings you're happy with, now if you're at 100fps with settings you like then great... but if your gpu is at 100% usage it is STILL a bottleneck, because if you put another card in there you will see massive gains in fps, it doesnt matter if the fps is 200, 300, even 1000, it's still a bottleneck because it's holding the system back
tldr; no matter what the fps, if your usage is at 100% the gpu IS a bottleneck, fact....
