As a man who owns a Wii, X360, PS3, iMac and a very capable PC laptop, I'd say "no".
Of all consoles I own (including SNES, PSOne, PS2 and X-BOX), I've never had more problems and frustration than with my X360. Honestly, I've even had more fun with my Wii.
And as for a gaming PC... I kind of think it's childish. Once you have a very capable computer (whether it runs on OS X or Windows is your choice), you get much more satisfaction in using that hardware to do more constructive things than playing video games. I think it's a waste, really... Why put all that money in a rig to play some shooter on it's highest settings, when you could learn digital painting, audio-visual post-production, 3D modelling and sculpting?
