Laptop Purchasing Help
 

Long story short, looking for a laptop. Basically, it needs to run Fallout 3. I have no real experience with laptop purchasing, and I want to make sure that I get something that doesn't suck.

I am trying to keep the price range to around $900 or so. I had my eye on a Lenovo Ideapad that just disappeared when I came back to look at it later. Good enough of a built in graphics card to last me through playing Fallout 3, Starcraft 2, and Diablo 3. 3-4 gigs of ram. Decent processor, etc.

So, those of you that are in the know, have some good ideas?

Thanks in advance
