Hey,
I have been wondering... why would you spend so much money on a computer to play a game when a console (xbox 360, playstation, etc) could pump out better performance for much less money?
Better performance ? Whaaa?
The thing that is annoying about consoles is you really can't upgrade them much like a PC. They are what they are. While the latest and greatest is cool at the moment, when the next big thing comes on you're stuck with the little $500 paperweight.
With a PC, if you build it up to today's "fast PC" standards, you can play the latest and greatest games (including the older games too which can still be great) but also you'll be able to play the future latest and greatest games if you simply bring your graphics quality down... And then you can upgrade over time. It's also fun building your own system, kind of like building a motor. Highly customizable.
For me PC graphics have always looked better than console graphics. That might have some to do with the high resolution monitors that PCs are played on, though I've yet to play a console game on a high def. TV set.
As mentioned before, MODS ARE GREAT! It's like getting a half dozen different games in one. And also there's a huge selection of PC games.
Keyboard and mouse is such a better control set up than a controller IMO. Especially with shooter games. For me it's always been so hard to aim with the directional pad/joystick setup.
Online multiplayer gaming is simple with a PC. Most of all I think very few people build a high performance PC for just gaming purposes, unless they got a lot of money to blow.
