I'd save the money. Get either a Radeon Rx 580 8GB or GeForce GTX 6GB. Either should last you a few years given your current uses. There isn't much difference between the two. So get whichever is cheaper.
If you have a regular size PC case. Go with a dual or triple fan model. They are quieter. If you have a small case get a blower style to get hot air out ASAP.
If your case has only one fan. Look at getting a second fan. Most cases take 120mm. The Arctic F12 PWM is an excellent value for air flow, quiet operation and high pressure.
