Hi there,
Actually if what you want is reliability and you will earn money from your work, I think is best for you to look into a Pro GPU, since they will give you more performance and stability in those softwares.
the 7700 will work with your rig, but like I said for working purposes it's not ideal, you should get a much powerful gaming GPU card like the 7950 or a good Pro GPU Card, if you are on a budget you can look into the FirePro v7900 which is based on the HD 7870 gpu chip, this will last you a good time
until you save for a new one.
You can also check the new line of Pro GPU, but they are expensive.
From experience I only use workstation grade GPU for my workstation because of those things
Cheers
