This "if you game on a PC then you have to spend thousands of dollars" thing is just laughable. The idea that no one can be satisfied playing on a PC unless they're running Crysis at ultra-high is a nothing but a preconception by people who don't know what they're talking about. It's as bad as saying all console gamers are 12-year olds playing CoD.
My gaming PC cost me about $300 over what I would spend on a normal PC. It's going to last me several years. I likely won't need to upgrade it but if I do then I'll buy something relatively cheap. Will I be playing on ultra-high? Nope, but I don't care and it will STILL look as good as most games on a console.
Meanwhile, I will have more games on PC at a fraction of the cost of my PS3 library. My Steam backlog is absolutely huge and almost all of them were incredibly cheap.
The thing is, which a lot of people seem unable to understand, is that the cost of PC gaming is highly variable. If you WANT to spend thousands of dollars then you can. However, assuming everyone has to have bleeding edge components is like saying everyone who drives has to spend $80,000 just because you know of a few people who own Mercedes.
