The intel hd 2500 should be sufficient to do those tasks, though it is a very low end Ivy Bridge IGP. At this point I can't really determine how powerful the hd 2500 is going to be, I'm not going to rely on benchmarks until Ivy Bridge is actually released.
I would recommend the intel hd 4000 chip, it will provide a 50% performance increase over the current IGP champion the intel hd 3000, and will satisfy all of your computing needs with ease.
I'll look for some more info on the 2500, I'm going to assume it has the relative power of an intel hd 3000, I'll try to find info to verify that.
