Want to play GW, but not sure if my laptop will run it OK

My laptop specs. Intel centrino 1.4 ghz, 756mb ram, and Intel Extreme Graphics 2 vid card.
Has anyone tried playing GW: Nightfall with a similar setup? Does it work fine?
For experts out there, do you think it will run fine?
If it doesn't, any inexpensive ways to upgrade to make it work? maybe more ram?
I just want to play this awesome game! but I don't want to go buy it and then try to play it and it won't work then I wouldn't be able to return it because it's open software.
Thanks!

It might be extremely laggy due to a lack of graphics card.

Intel Extreme Graphics = Integrated graphics. This means it has no physical board and uses main memory also.
