The point of PC gaming is to play the games you normally play at 1080p/60fps. The choice of games you gave him was, to be blunt and silly, super retarded. +1 to the person that said you should spend a night in the cells for this outrage!
My girlfriend is an avid gamer (mostly console). However, she is mostly a lazy gamer recently, so she's happy to sit and watch me play games (win-win for both of us since I get to sit there gaming sometimes

). I recently took my PC to her house for 3 weeks since her mum was away, so we were playing stuff together every night (Silverstone Raven 3 across central London = not fun at all). Near the end of the 3 weeks I turned to her and said "1080p, 60fps, do you understand why I spend so much time with my PC now?" and she agreed wholeheartedly. I even switched the game to 720p a couple of times to show her what a console version might look like and she agreed it looked horrible.
You really don't have to spend too much time or money with your PC any way. Spend £1,000 now (or much less if you want! If you already have the big TV with your consoles £500 will be fine) and you're going to have a system that is fine for years. A day setting it up, then just clean it out (you should be cleaning your consoles anyway!) every now and again.
PC gaming is also cheaper. £30 for NEW releases and they drop in price just as fast as console games. Even if you only bought 10 games a year, over 3 years that's £300 saved on software. If you wait till Steam sales, you can spend £50-100 and have enough games to last you all year.
Try doing this with a console gamer: set something like GTA IV or Call of Duty to play on both a console and hook them up to a HDTV. Flick between them. Plug a 360 pad (or even a Ps3 pad) into the PC. Then try to tell me why you're gonna stick with your console.
But ANYWAY... I game on consoles all the time. They're very convenient and easy to set up, and there's lots of games on them I can't play on PC. I have both a 360 and a Ps3 waiting for me when the mood takes me

And ANYWAY... as long as you're enjoying your fantastic gaming time, then GOOD
