Which should I buy?

Over the past several months, I've been juggling multiple jobs trying to save up a good sum of money to buy something nice for myself! I have a total of $850 but I would like to spend it all on one of the following...

• Additional hardware for my PC (External hard drive, video card, etc.)
• Nintendo DS lite
• PSP Slim

At the moment, I have a Dell Dimension 4700. I thought about just getting a new computer all together but that would take all of my money and I wouldn't have enough to buy games to go with it. Besides, buying the additional hardware would make my computer better than anything I could buy with $850 dollars, and it would be cheaper.

I bought a DS several days after it was first released and I really enjoyed it. It was the most innovative handheld ever released and a lot of my favorite game franchises would be making appearances on it. Sadly, I loaned it to a friend because he was going out of town and wanted something to do on the plane ride. When he returned, I discovered that he sold it "used" for some extra cash. (Yeah, some friend he turned out to be.)

I never quite been much of a Sony-type of guy. I don't have a PS, PS2, or PS3. I was thinking it would be nice to give the PSP Slim a test drive, but I don't want it to come back and bite me in the ass later on. The PSP has a lot of multimedia features which would be cool. I don't have an MP3 player of any kind and so the music and videos would be awesome to have when I don't feel like playing games.

So, there you have it. Some input would be nice of what you think would be the best choice for me. I don't want any flaming saying "DO YOUR OWN RESEARCH, N00B!!!" I have done my research but I want opinions from people who own the product and know exactly what it's like.

P.S. If I were to buy a PSP or DS, I would spend the additional money on games and extra crap for it.

First of all, that 'friend' is an A§§, I would have forced him to pay me back a DS.

I dont know what kind of pc youve got so I dont know how much your going to be spending on it (only a g-card, only more ram, maybe both, I just dont know) However I wouldnt buy both a psp and a DS, their both there to make travelling go faster and are fun to play with when having little spare time on the move, so just choose which one u like. I myself bought a DS but somehow I think a psp would fit me better cause ive got the feeling that all that is comming out lately is just the same braintraining game and the 1000th version of a 2d rpg with some 'cool' new way to use the 2nd screen. Some might say the psp wont be getting a lot of new titles but therell be God of war, and there still is: Tekken, PES/FIFA, GTA, Ridge racer and more to play which is more appealing then the games the ds has to offer. I cant / wont be telling you to buy a PSP im just sharing my thoughts but first of all, if I where you id upgrade my pc cause theres some cool games comming out. (Assasins Creed, Crysis, Bioshock, Orange box) and then if theres maybe a buck or 300 left I'd spent it on a psp with Tekken, GTA and fifa.

Hope it helps you:)
