I just looked up the system requirements for Crysis and I see no reason why it shouldn't be able to play it on low to medium settings. Keep in mind that laptops just aren't really made as gaming platforms (unless you're willing to spend A LOT of coin for one). The graphics card is actually fairly decent for a laptop though and comes with Shader 4.0 is a DirectX 10 card... So it's at least one of the better video cards you can get in a laptop.
I did some checks on the card, and here's a page I found that showed some interesting benchmarks:

As you can see, Crysis is actually listed as well as a few other graphically intense games like F.E.A.R.
To answer the question, you shouldn't have any problem playing BioShock or Crysis now.. they're already relatively old games, and the orange box you should breeze through with that kind of card. In 2 to 3 years though, you're probably going to be looking at an upgrade again.
The thing about any laptop used for intense operation is that they only have a shelf life of 3-4 years before you start noticing them getting quite laggy in game play. So at that time you might be able to play games on the lower settings, but the processor is going to be holding you back (both the graphic processor and the CPU).
Now the only other thing is that it's only a Dual Core, and it's only 2.0GHz.. Not a huge issue, but definitely not top of the line. It should still be able to do quite a few operations without getting extremely slow.
It's not an incredibly BAD laptop, yes there are better ones out there for more money, but if you're trying to find a cheap solution that can do what you describe you want to do, go ahead and get it.
