Laptop help please

I just got a laptop for my birthday purchased from ebay and it is a
IBM ThinkPad T23 Series


--
now
the only thing i have concerns with is the graphics card because I know to play a lot of computer games out there i need somewhat of a decent graphics card. It comes with a 16 mb graphics card(i am pretty sure).

do any of you know if i would be able to upgrade this?

(yeah i know its not a real top-grade laptop, ill list some specs though just so you know what I'm working with here.)


just look below and tell me if you think id be able to pop in some blizzard games and play away (warcraft III, D2(LOD - ofcourse), starcraft.. things like that) or if i would have to probably find and purchase an upgrade for it first.
