Lenovo is not a computer - it is a company that makes computers, many models of varying price and performance.
Also, why are you getting a laptop?
Your AC will require some pretty heavy duty graphics processing, the kind that's very expensive on a laptop. In any PC, graphics requires some kind of graphics chip and RAM. On many budget desktops and most laptops, the chip is embedded on the motherboard, and shares system memory - this is "integrated graphics". It may run AC, but probably at an unacceptable speed. The alternative is a dedicated graphics card - common to desk machines but not laptops because they consume battery power faster, generate more eat and are heavier, bigger and more expensive than IG laptops. Macbooks come equipped only w/IG on all but the Macbook Pro models, and you'll need to think very carefully about whether the cards on the MbP will work with AC (I think it's the Geforce 8800GT - check for reviews on the web using AC and that card.)
Why are you leaning towards Lenovo ahead of all other PC laptops? If you haven't settled on a model yet, you shouldn't be limiting yourself to a brand. Some Lenovos (like most in the PC world) come with dedicated graphics, some allow for graphics cards.
