This guy has NO idea what he's talking about. Sorry dude....
PS3 - 500
360 - 479 (elite)
Wii - 250
PC - 100-250 for a decent mobo
300-400 for a decent video card (mine was 500 at the time I got it *X1900XTX*) Now they're DX10, so you need
a DX10 card and board
my processor was 468 when it was new (X2 4400+)
Fast Hard drive (raptor 10krpm - 100-200 bucks)
You need a case, monitor, peripherals, drives, etc. For a rig that will even be
comparable to a next-gen rig would cost at LEAST double...and games are usually only 10 dollars cheaper........I mean c'mon.....
I paid about 2000 for my rig when I got it all brand new(not including monitor(~300) or peripherals(~100)). It was the best of the best, and is already outdated HEAVILY ( Now there's: DDR2 hyperdrive chips, quad cores, directX 10, etc. etc.) My rig is only 1.5yrs old. the PS2 came out in 1999 and STILL has games launching for it. The normal life expectancy of a console is around 10 years (which wasn't the case for legion's beloved failed dreamcast...) So, not only do you get that, you get this:
Uniformity. Because so many computers are running so many components, developers can't optimize for one rig. They have to make it run evenly across the board, which hurts most high-end rigs... *Remember the Oblivion Framerate nightmare?* Consoles are made EXACTLY the same, so developers can squeeze every ounce of power out of the consoles, and make them run smooth as silk every time (because they can't test 10 million different hardware configurations).
Get a Wiii
for the kids and be done with it.
