Hi! I'm looking for good video card for my Inspiron 580 because I going to make video editing with Sony Vegas Movie Studio 11 Platinum but I don't know what card better for my future works

how big is the PSU? if I am not mistaken it is only 300W

is it a slim case?

Now I have 300w PSU but no problem to upgrade PSU. I like NVIDIO PNY 600 but I don't know - this card will work in my computer?
