[Rollercoaster]

Go for
Amd 3200+
Asus A8N-E or SLI
XFX 6600GT 128MB PCIe
1 GB DDR400 Ram of ur choice
buy 2 SATA HDDs so u can rig 'em up in RAID0 as nforce4 mobos support inbuilt RAID...(good for games with large level loading time like DOOM3)
Buy a Wireless keyboard/mouse set with an additional optical wired mouse(some games show lag while playing via wireless Input devices)
450Watt SMPS for non SLI and >500watts for SLI mobo
Buy a decent set of wireless/wired dolby headphones and insted of buying a expenseive speaker set rig up ur Home stereo system and with PC too good if u have one of those boombastic hifi mojo rising music systems...
Buy two monitors.. atleast 17" or one 19" and the other 15"(or 17") or but a 14" or 15" LCD with a 17" monitor and rig both of them up to ur graphic card so that u can make some really serious looking setup... and do some really serious work too(dude this is real multitasking) .....
This is very helpfull as u can do more than twice the stuff then u do on one screen man!! and a wirless keyboard/mouse will compliment this setup very nicely...
Get a decent TV-Tuner too (go for the media center kind .. really neat to control ur PC via remote, all that S#$% like music,movies,photos,TV etc.)
Alsi get a DVD-RW and a DVD-ROM to complete the rig...

NOW u can go on living a dream......
