You're not going to be doing any "high level" gaming on a GT 440. It's a very weak card.
It can't even handle high settings at 1280x1024 on demanding games, e.g.
You will be able to play older games and games with toned-down detail settings at 1280x1024 or lower resolution. It won't handle anything demanding at higher resolutions. It's about 20-25% as strong as a GTX 580/HD 7870/GTX 660ti.
Unless you're planning to get this GT 440 for $50 or so, there are FAR better budget options for you out there, namely the Radeon HD 6770 or 7750 - both of which can be had for $100 or less.
