Hey ginjirou,
PC gaming' s an expensive hobby indeed, but these days console gaming is catching up! They' ve realised that powerful hardware comes at a price, but instead of paying the price up front for the hardware, you give it back later on other things.
I' ve kept my PC going for about 2.5 years with minimal upgrades (a gfx card upgrade to 6800gt) and I reckon you could do the same for about $1500. Pre-built machines for gamers are becoming cheaper these days from the likes of alienware and dell, but they often cut prices using cheap components. But building your own can come with its own hassles.
My current setup (2.8G intel, 6800gt overclocked, 1G Ram) can run the new Need For Speed on full, with just as much quality and smoothness as the 360 version, and could be built for around $800 these days. Half-life 2 and doom3 engine games run flawlessly as well. Im expecting another 1/2 year out of my setup before I have to turn down graphical features.
But... I would go for AMD 64 for a cpu, intel are more expensive and give less performance atm... and 2G Ram.
Id say that yu might be disappointed with the nvidia 7800gtx' s image quality tho, ati' s x1800xt is often regarded as the better choice. If you want something to rival the xbox360s potential, then you should aim at an ati x1800xt ' pe' or higher.
The ultimate gaming rig atm would be AMD fx-57, Crossfire 2x x1800xt pe, Crucial/Corsair/OCZ 2G Ram, Audigy 2 ZS (some say its still better than the X-fi!). This would rival the 360 for the next few years at least, but would cost over $2500 at the current rate! ($500 for PS3 doesnt sound so bad now eh?
)
In the end it just depends what games you like and how you like to play them. Currently for no hassle super gameplay, the new consoles will rule, but I find there' s something different enjoyed in PC games thats worth the extra cash. Still next-gen is gonna be expensive for PCs as well as consoles. Hope this helps.
