Will multiple cards (non-CrossFire) improve multi-monitor performance?

I am currently using a Radeon HD 7870 with 6 ports to drive 5 monitors (4 are quad HD).  I have a spare HD 7770.  I have heard that multiple GPUs will actually hurt performance if you are not taking advantage of the extra power.  I am not doing anything graphically intensive other than driving a lot of pixels and heavy multitasking.  I do not use Eyefinity.  Will I benefit from adding the 7770 to my rig and moving two of the monitors to it?


In case it matters, other components:

- CPU: i7 3770 @ 3.4GHz

- Mem: 12GB DDR3 1600 CL9

- MB: Asus P8Z77 WS

- PSU: High-quality 750W

+ 7870 has 2GB of GDDR5 and 7770 has 1GB

(basically, everything was high-end back in 2013)
