Alienware's high quality man, I'm sure they shipped it with if not new already then pretty new drivers. Of course getting the latest is always good.
Now.. new computer trouble, but you forgot to mention what's the problem.. do you just want to know if you need to update more computer components in order for it to work better?? it's understood that the newer the drivers, usually the better. I've had some hit and misses with nvidia and ati drivers. (catalyst v5.1 sucked on my comp, lost 10F/S permanently on halo, aboot 8F/S off BFV.. yeah. v5.2 was ok though, everything up's fine.
Later-A-Much, and LONG LIVE THE D!
