Fixed.
I bought a Core i7 with a GTX460 and 6GB of RAM, plus a mobo, and a HDD, and a DVD drive. And a red LED fan and red lights for stuffs and giggles. Total: ~$1000. I also only bought the HDD and DVD drive because I was running out of room on my 160GB and the new mobo didn't support IDE DVD Drives.
For about $500 or less, you can get a quad core, new motherboard, a nice graphics card and 4GB of RAM.
You don't have to upgrade it with every new generation of Intel processors that come out or whatever. I'm probably not going to upgrade my processor and RAM for a LONG time simply due to the fact that they don't need an upgrade. GPUs, however, are really flexible for upgrading depending on how much you dish for it.
Oh and
keyboard and mouse.
In other words; you are all mad because other people have better computers.
