sure PCs you can upgrade to the infinity, 16GB of ram, quad GPUs whit 2GB of DDR5 ram each, ultra fast 500mb/s SSD hard drives, multiple core CPUs at over 3Ghz each core(and a price tag running nearly on the price of a small car) consoles give you very VERY good graphics for a mere 300 dollars, thats whi the incentive to expend several thousand dollars on top notch PCs is vanishing, and if the succes of the wii tell us anithing is that horsepower not neccesarily mean better, ill play mario galaxy any day over Crysis, and im pretty sure Uncharted 2 and Gears of War 2 look a hundred times better than ANY PC whit a 300 dollars price tag, so until you can build me a PC at that price tag that can give me the same performance im not gonna be convinced (and the same amount of games because lets face it each year there are less and less PC "exclusives" really worth it, and even less that really could push that brand new 5 thousand dollar monster you just build because you could)
PS: have you noticed that PC gamers have been usin Crysis for over 3 years now on theyr cries of PC is better than consoles? (there isnt any other game that really push computers?)
PSS: i have a decent rig for work purposes (i just added an average GPU for gaming), Core i7 6GB DDR3 RAM whit a Nvidia 280 1GB, 23 inch led monitor, 500watt THX logitech speakers, not TOO spectacular but it run Crisys like butter, and just about ANITHING i trow at it at maximum quality (as long as i dont get too greedy whit the resolution and AA/AF wich at 23 inchs is no too neccesary) also have all 3 current gen consoles and the one i play the most is my PS3 (online mostly) second my 360, faaar third my WII, and FAAAAAAAAAR fourth the PC (only game i really played in the last two years is StarcraftII)
