With that resolution you can run your games at high settings...have you ever considered buying 1080p LED monitor? 22" go for $130ish
If it were completely for me I would probably do that. However it is a family PC that will mainly be used by my mother for her picture editing. The monitor we have will do just fine for her purposes. That being said, I do hope to have a 2000ish dollar budget within the next few months to build a computer for my college career, in which I'll be back for more advice.
