A faster processor is what you want, but that PSU is downright anemic (by comparison, I have a 600 watt which is admittedly more than most people need). You are going to have to upgrade that before you do anything else. 
 

More RAM is also nice, and will help with GTA IV immensly.

Cake!!!!!!!!!!!

Well, Radiohead is the first thing that pops into my mind, but you probably already know whether you like them or not.
 
Joy Division fits nicely into your "quietly messed up" category, though given that the lead singer hung himself I don't know how quiet it really is. 
EDIT: Its better if you don't watch the pics in thsi video.
 
 

Can you imagine yourself actually playing a 2-4 hour game like this?

Foo Fighters, specificly Everlong.

So, I'm working on this game. Its a game play idea I've had for about 2 years, and a story idea I've had for 1 year. Obviously at this point I am horribly married to it and could not possibly be able to tell if it is going to work or not. What we have here is a little powerpoint that I have built from my design document as a Proof of Concept. It explains itself, so I won't go into it to much, but rest assured it isn't like anythign you have played before.
 
Please be brutal, I don't want to spend the next year and a half of my life working on a game that turns out to be unplayable.

I suppose, it was just an idea. At least I get to show off my fancy little chart :)

I finally got around to doing this guy up, and had an idea based on another Giantbomb thread. Take this flowchart and do whatever you want with it! (The download link is to the original DOCX file, but you can edit the image in photoshop if you'd like)
