Simple yes/no question pertaining to gaming. Standard resolutions, lets say 1080p just for consistency.

In terms of CPU/GPU, specifics irrelevant. You have a rig in which your GPU usage is pinned at 99% max load. Will you ever gain noticeable framerates by upgrading your CPU?

(yes, I asked this in the processor forum last week, but was unaware how terribad that section was and received a whopping 8 votes to date.. so reposting!)

[edit]

I look at it this way: CPU is a conveyor belt, and the GPU is a mechanical painting arm(lol). The CPU cranks 50 blank canvas on its belt per second, and the GPU is capable of painting 50 per second. Up that belt speed to say 100 canvas/sec, and the arm can still only paint 50.. you won't see any increase in productivity.

Pretty obvious what side I'm on. My friend then makes the argument that theres a third factor: the canvas are rotating on a pivot while going down the belt. And upgrading the belt to slow down the spin prevents the GPU from having to steady it before it paints.. so it slightly increases productivity despite arm not increasing its load.

Or, to simplify our retarded analogy: its not just CPU/GPU(my view), and there are some processes that require both to work together. So even a max loaded GPU can benefit from a faster CPU (his view), to which I would counter that is not major principle of performance. Round and round we go~

Hence the poll

I say no. Maybe 2 or 3 FPS max. I think it's possible to gain a slight improvement but nothing substantial or even really noticeable.

Nope. If your GPU is maxed, adding power to your CPU makes negative sense.

Depends on the game. FSX for example is poorly written and very CPU intensive.

I wouldn't be surprised if it is one of those things that depends on the game. That 99% load could just as well be the gpu fetching data from the cpu and waiting.

It might help with minimum frame rates as well, meaning that while your frame rate won't increase across the board or see a higher maximum, it might be more smooth/balanced.

I myself kinda wonder bout this. While running a GTA IV benchmark I noticed video memory was 99% but cpu usage was only 53%. Guess thats not necessarily gpu usage but still.

I only voted yes because it depends on the game, such as someone else said.

If I said no, then I'd be lying.

I've been thinking about this for a while, mainly because I see a lot of people that upgrade to SB and wonder why they just don't spend that money on a better GPU. Obviously for gaming that would be a better choice, but I guess not everyone just games on their PC's

Yes and No its not a real clear answer lower res require more usage from the cpu compared to much higher ones where the gpus are taxed alot more. While its not a game but a benchmark is 3dmark06 its very dependt on the cpu heck my trifire with a i7 only got 28k but iv seen 470s in sli with a sandy get 30k.
