Well haxer : to my own experience you have given the answer of what we desgree with each other :
1- Crappy PC, is not for gamin, even if boosted with heavy techs
2- even New PC's wich supposed to be games oriented are not really for that, simply because some games are made for Consols, take a look :
Can you play God of War in PC? ....No, agree, it's the same opinion of the developpers wich made it only on PS2 !!!
in a way, PC's are great for games like strategic ones : take for exemple c&c générals or reflexive ones as Crosswords!
for you PC haxer, note one thing : as speedy as things are going on, you heavy techy peripherals will be out of date in about 3 or 4 months. can you say the same about PS3 or XBOX???

I'm gonna have to side with Haxer on this one - In comparison, a dedicated gaming console has pretty inferior specs on its graphics cards and central processor, and is usually less than 1/4 the RAM on either. PC's, although they can be finicky when it comes to setup, still have the greatest opportunity for high-end experience. There isn't a gaming console I know of that can do SLI - 2 or more graphics cards. A gaming console might push HDMI standards, but a gaming PC could power the same game on wrap-around 1600x1200 monitors (3 or more - I've seen one person run an astounding 12!!!).
Consoles are the way to go for no-fuss gaming, generally, but a PC platform can offer 10-1000 times the amount of pixels and vertexes being pushed around the screen. Another trade-off is cost, of course. Getting a dedicated console can be 1/5-1/10 the cost of a gaming computer.
...but, you CAN modify a gaming PC without voiding warranties!
