Guess I'm way too late, but for anyone looking with a similar question looking up this thread:
Equivalent cards to the integrated graphics would be about the GeForce 820M, or if you're looking at non mobile that would have to be something relatively old like a GeForce GT 710. People here who say there isn't a card worse than the hd 610 integrated probably never looked at the absolute bottom tier, 800M for example is outperformed by the hd 610. with non mobiles you'd have to look at a low GT older than a 710.
