Hey guys, My birthday is coming around (The 27th of December) and I am thinking about getting a new computer and pooping on this one, I'm currently using cause it's from the STONE Age. I mean seriously, You guys will cry when you read my specs or Running will find out where i live just to smash it. Here it goes:

Processor: AMD Athlon(tm) Dual Core Processor 3350e (2CPUs), ~2.3GHz
Graphics Card: GeForce 6150SE nForce 430
(No more as it's too shitty to be known for, This computer is about 5-7 years old D

Games I would enjoy playing:
Red Faction: Armageddon
Metro 2033
Arma 2 (Would be nice)
Grand Theft Auto 4
Garry's Mod (My Gmod's frame rate goes down cause of the new update so I can barely play it anymore)
Men of War (I can play this but on LOW graphics :b)

And other Medium/High Graphic Games, I don't want Highest Crazy Ass Crysis Graphics, I just want to be able to play the game on Medium to High and Not see the world look like a 2 year old who drew the floor with crayons. I don't know a single thing when it comes to making a "NASA Computer" and You guys can judge my poopy computer but atleast try to help me out.

I'm talking about a budget of around 500$ to 600ish$ Help please! Thanks guys!
