Quick game requirement question

[Sarevok]

I had been out of the loop as far as playing new games have been concerned. Right now I have no idea what constitutes minimum requirements for gaming. Recently I got a new laptop which has an Intel Centrino cpu with 2.536 GHZ speed, 4 GB ram and a Radeon 4500 video card with 512 mb dedicated memory.
Can this laptop handle the following games

- Mass Effect 1 and 2
- Prototype
- Assasins Creed 1 and 2
