Hey guys noob here just a compatibility question.

Solution
If your motherboard is SLI compatible, you have sufficient PSU and your CPU has enough power to run GTX-650's in SLI then yes you can add second GTX-650.


According to tags that he added he probably have 760G or 970 AMD chipset with FX-6300 CPU and I think his motherboard doesn't support SLI.

OP what PC components do you have?
 


You have an APU which is not so good compared to Intel CPU's A10-7700 will bottleneck your GPU's.
