2 part question need to order parts tonight! MOBO / GPU

Putting together a computer for a business, or, just ordering the parts rather. I have 2 hopefully easy questions that need answer.

1. Is this MOBO (MSI A68HM-GRENADE FM2+ AMD A68H 4 x SATA 6Gb/s USB 3.0 HDMI Micro ATX AMD Motherboard - Newegg.com) Interchangable with this MOBO? (MSI A78M-E35 V2 FM2+ AMD A78 6 x SATA 6Gb/s USB 3.0 HDMI Micro ATX AMD Motherboard - Newegg.com)

2. I need really damn cheap graphics card that I can successfully have 3 independent monitors on. Can I get a recommendation with the MOBO I posted above?


Here's the CPU for the unit:

AMD A10-7850K Kaveri 12 Compute Cores (4 CPU + 8 GPU) 3.7 GHz Socket FM2+ 95W AD785KXBJABOX Desktop Processor AMD Radeon R7 series


Thanks a million!
