First thing. Next time you post something on the Forum please use a better description than serious help needed, something like laptop advice needed or laptop buying advice meant of been better. Secondly you say you have to buy it today. Well its 4.20PM so you're a bit late deciding to post.
Regarding will the laptop do then the answer is yes BUT I have to point out that laptops are not all that great at playing games and you mention Football Manager, theres quite a few Football Manager games out there. As I've never used any of them I don't know what they require in the way of graphics and its the graphics that are going to be the problem.
For everything else the laptop will be fine but I think I also should mention that Vista requires good graphics to use all its bells and whistles and although Vista would work on this laptop you may find some of the advanced graphics facilities do not run.
