Mainboard Model - Gigabyte G41MT-S2PT
4GB ram
Intel® G41 Express Chipset

My goal is to find the best possible GPU with no external power.

  1. What is your PSU?
  2. check the 7750.
  3. Here is the thing. Your motherboard's slot for GPU is PCI express 1.0 x16 and the GPU that you propose has PCI express 3.0 x16 along with the majority of all the GPUs this period. The good thing is that PCI express is backwards compitable so the 3.0 will play in the 1.0. But it is very logical that it won't work on its full potential, it will work with the 1.0 standards. So it may not reach your expectations. Also you got to give us more info about your Power supply unit because it might not be able to give enough power to your GPU.

    To sum up if you have a decent PSU then this GPU will work fine but not at its full potential.

    Ok dude my bad didn't read the description carefully. You don't have to be so salty about it, I'm trying to help. But you are right HD 7750 is better than GT 640 . Also OP asked if the GT 640 works for his system which I answered...
