I just ordered a new PSU so I would have enough power to upgrade my GPU, wondering what the best bang for my buck in the 200-300$ range.
Here are my mother board specs and my new PSU specs for compatability

I also have a fairly small mid size ATX case, and it will be a tight fit if i get a larger PSU, so feel free to reccomend some nice looking cases, (preferably cheap)
Edit: Prices in Canada are much much higher, a 280 usually goes for around 330.
Right now I'm considering a Radeon 7950 for 260$, a GeForce 760/ or 760Ti, or an radeon 270x.
