I can't decide! Zabrak Marauder, or Assassin?

Im not that great with computers.. *Facepalms self* What is a "Driver"?

Anyone think my HP TouchSmart 300 can run this on Low? If this helps it can run Wow on Medium everything... no Lag

I have a modern computer I suppose.. but it is just hard to have good graphics.. I can't change the graphics card because it is a single unit comp*.. (That means it has the moniter and everything else in one unit) I am just hoping to be able to play in low graphics. It's a HP TouchSmart300, not the best of my spending...

Hmm... I think i'll make a Sith Assassin, but another question... what RACE? I have decided between Sith and Zabrak.. I love Darth Maul but the guy in the trailer looks pretty good..
