Hi cutepathogen,
A 580 is a solid initial CAT score (the average score on the Official GMAT hovers around 540-550 most years), but raising that score to a 720+ will likely require that you make significant improvements to how you handle BOTH the Quant and Verbal sections. As such, you will likely need closer to 3 months of consistent study (especially if your real goal is a 750+). You don't have to make any decisions about that just yet though, so you can certainly study as you choose. As an aside,
