Hey guys, here's the list I could use some suggestions, as I'm thinking maybe I should step down the card from an R9 290? She loves playing Heroes of Might and Magic 7 and I'm looking to give her a computer for cheap that'll last her for quite a while

Please keep in mind that the "Purchased" parts cannot be changed as I have them lying around and that is the whole reason I am doing this build.

Get a FX 6300 or atleaste a i3 and change the gpu to a 380, she isn't playing games at ultra 1080p 60 fps no?

put some more juice into the cpu than gpu
