Got in too not surprisingly. I get into Battlefield shit easily. Late to the party as I signed up for the newsletter at the last minute but I'm in!
If you can run Bad Company 2 well, you won't have a problem with BF3. I rate the alpha's requirements just slightly higher than BC2s. I may be wrong and the full version needs a super computer, especially if you max it out (currently no visual setting that makes it look as amazing as the videos).
