Is my board compatible with this GPU?

Is my Asus M2A HM HDMI compatible with a Radeon R9 290x or Nvidia GTX 790 ti?

Yes it is compatible. But the question is is your CPU compatible? Your MB only supports AM2/AM2+ which is a generation old CPU. It could bottleneck with that fine young graphics card.

My CPU works fine in my opinion, is my board compatible with 16 gigabytes of ram?

 

[Adrian Ocampo]

Yes it can support up to 16gigabytes of DDR2 ram.
