If you aren't gaming then you don't need a very powerful card. Something like a GT 220 would work well.
As you suggested, I've been looking at GT 220 cards. Do you, or does anyone, have an opinion as to which of the following would be best for my purposes? Is one of the manufacturers more reliable than the others? Is one of them quiter than the others (noise is a factor because I'm operating in a sound studio)?
(1) ASUS ENGT220/DI/1GD2(LP)
(2) BFG Tech BFGEGT2201024D2BE
(3) Galaxy 22TGE8HX2IUN
