Looking to play EQ2 at "good settings" and now it's "all games for next 3 years" is a bit different.
Look at the benchmarks for the different video cards, get the fastest one. There are new chipsets and video cards coming up every year, heck every half-year. The 560M is a good card, but not the best. http://www.notebookcheck.net/Comparison-of-Laptop-Graphics-Cards.130.0.html
If you want something that will play any game on high settings for a few years, you really need to get a top of the line or very close to it card today.
