What the hell? It was a question , a serious one at that. I'll ask somewhere else if its such a problem
Unfortunately questions like this come with a TROLL tag attached automatically and get treated with that level of disdain.
There are thousands of websites out there that can provide the information that you require, it just takes a little research.
As a clue, look how much PC technology has moved on since the launch of say the XBox in 2005
2005
GeForce 7800GTX
Athlon 6400 4000
2010
GeForce GTX 480 1536MB GDDR5
Intel Core i7 980X 3.33GHz
As the XBox 360 and PS3 have barely moved on (there have been some minor revisions on die size etc) in 5 years, and the PC Market has probably moved on 4 or 5 generations of architecture overhaul, do you think that they will be behind the level of technology of what are in PC Gaming Terms, old rigs ?
If you agree that PC technology has probably come a long way in 5 years and that console technology has barely moved at all, then the principle of Occams Razor says that PC technology beats console technology (hands down).
So to answer your 'dubious' but allegedly serious question, a modern PC gaming rig, lets say for arguement "Ultima Divinity" Intel Core i7 960 D0 Stepping 3.20GHz @ 4.00GHz Quad Core DDR3 System sold by overclockers £3098.49 inc VAT will not only kick the XBox360 and the PS3's butt with its hands tied behind its back, it will dance on their graves and build a nuclear power station on it afterwards to boot ! (which you would expect as it costs nearly 6 times the price of buying both an XBOX360 and a PS3 at the same time)
