Can I play big games with this computer?

My laptop is an acer aspire 4738Z with 100gb available on both drives. My connection speed is 100Mbps. I think this doesnt have a game graphics driver. So I wanna know if I can play "big" mmorpgs with this and what game do you reccomend. I'm no spender. I think I'll play guildwars 2 when it comes out because it seems like it has ample pvp which i like, I dont like grinding and boring gameplay where you basically have to do that things you're told to to get more powerful and you just have to press a button and you'll put out a string of attacks. I want a game that involves some skill... Ty in advance. :)
