Personaly id go for the hard drive, i am stuck with a 9 gig drive myself. Its just not enough, not with the amount of games and add-ons i have ended up collecting.

Im using a 450 mhz CPU, with a voodoo banshee card, and it works fine on just about all games. (I can run Quake III acceptably, anything on the infinity engine works great, I meet the specs for NWN, what more do you need), but if you have something below 300 then you might want to upgrade the CPU instead. One thing you might want to watch out for is needing a new motherboard - unless you have an athlon already youll definatly need one. You might need one even if you do if its a real early board. If its Slot A for example. I think even the early socket As are good up to 1.1Ghz.
