My computer gaming rig costs less than $800usd with accessories and all, and I assure you I hold up with the best of them. I built my own (saves a LOT of money) rather than buy some under-powered, over-priced, computer that's coolest feature is the case. No offense to those who do buy those types of things, but if you really looked into it, DIY is far cheaper with better results.
I don't even own consoles anymore. My last console was a Playstation...one. I do miss Tomb Raider, but PC gaming still trumps consoles.
