so i have a totally beast cpu, and when i game, there is only a small ammount of load on like 2 of the cores ( it is a 6 core) while the gpu is like maxed out and overheating. how can i make the cpu help out the gpu a little bit?

You can't, the game has to be designed to use multiple threads.

Also you are in the best scenario, the GPU maxing out is what you want, if the CPU were maxing out and not the GPU that would be a bottleneck.

it still is a bottleneck though...

Yea you are right, but the better of the two bottlenecks. It's much worse to have a CPU bottleneck.

so there really is no way to do this?

No, the game has to be written to use multiple cores, its not the fault of your system. Example play Crysis 3 and its likely you'll see 100% usage on all cores, go and play something like TES Morrowind and see 0% on everything but the first.

No way, sorry. However, you can always replace the graphics card with a better one. $400 buys a very decent graphics card these days, for example. Maybe you can even put TWO cards in (i.e. Crossfire or SLI), if your motherboard has two PCI-E x16 slots. What kind of motherboard, power supply, PC case and graphics card do you have right now?

i have 2 pci express 2.0 slots one at x16 one at x8.

What the CPU and GPU do are totally different, so that would not work anyway.

The CPU might have 6 cores, but the typical GPU has hundreds. 1,024 for my HD 7850 (which is NOT bleeding-edge). A CPU core can do the same work of a GPU core* in the same period of time, (assuming equal clock speeds) so using my system as an example:

900 MHz GPU clock frequency
4.3 GHz CPU clock frequency
4 cores in the CPU
4.3 x 4 * 0.9 = 19.1.

In other words, in my case, I'd be adding about 19 cores worth of work capacity, to a card that already has over a thousand. A drop in the bucket.

*The CPU is designed to handle complex instructions, in a given amount of time. It can do simple instructions as well, but not any faster than a complex instruction. GPU's thrive on ridiculous numbers of simple instructions.

thanks for explaining that
