2 different gpu's on one system non sli, Performance.

I know you can put two different gpu's in one system, non-sli. Will there be a proformance increase, or will they act as two separate gpu's? This is for gaming, not content creation.

Well you can have a primary card then a weaker card dedicated for PhysX (Nvidia only), what are the 2 cards?

I have a gtx 650 2gb, and wanted to add a 750ti, primarily i want to be ablo to heighten fps in graphically intensive games such as BF3 and 4, and Bioshock Infinite

You can use multiple cards like this for different purposes.
PhysX can be offloaded to a second Nvidia GPU as mentioned above.
Typical use though is to drive another monitor from the second card.
This won't help with games on your primary monitor at all, for that you need SLI or crossfire.

The GTX 750 Ti is a good step up from the GTX 650.
Remove the GTX 650 from the system as it will no longer be of use.

Alright but i have a 500 watt non 80 plus psu, if i remember correctly it 24 amps on the main rail, i don't remember voltage, will it work with out psu up grade?

The GTx 750 Ti uses less power than the GTX 650 (60W compared to 64W), so if the GTX 650 currently works you can safely replace it with the GTX 750 Ti.
