2 diffrent GPU

[sojle]

Hi guys I just wanted to ask you a question about gpus,I have two completely different gpus on my pc,one is AMD Radeon HD5800 series(1gb),other one is asus geforce 2gb gdd5,will they give any performance boost?One is SL,and my motherboard only supports crossfire-x,but I am new to this and I was just wondering if it would work.

No they wont give you any kind of performance boost.
But you can assign them to different tasks... So it kinda uses both... and stress less the another one...
But they dont work as SLI / Crossfire does.

Oh ok,so maybe its better to just have one of them in my pc?

Not really. With multiple GPUs you can run additional monitors. But most games will only run from a single main display adapter and primary display.

For compute tasks that are platform agnostic you can use any number of GPUs. Doesn't sound like you have anything high end, so probably not worth it there either.

For gaming, only common multiple GPU setups are Crossfire (AMD) and SLI (Nvidia), which typically require near identical graphics cards. In those situations you usually have each card rendering ever other frame, and each must have a complete copy of the memory of the other.

DX12 has opened this up a little, but there aren't any games taking advantage of true multi-GPU rendering (Where it treats all graphics resources as a pool to be used)
