thanks for the input. I may go with something like that, or possibly this:
GIGABYTE GTX 650 ti 2GB http://www.newegg.com/Product/Product.aspx?Item=N82E16814125446
It is miles ahead of my current old video card, and because it supports vga I wont have to buy a monitor just yet, and when I do get an HD monitor, the card will be ready for it.
Leaning towards the second option, as the 650 ti price range is something I can do more easily right now.
