As far as the main components go the best bang for the buck in intel land would be these
CORSAIR VALUESELECT Kit 240-Pin 1GB(2 x 512MB) DDR2 PC2-4200
ABIT "AA8-DuraMAX" i925X Chipset Motherboard for Intel LGA775 CPU
Intel LGA 775 Pentium 4 530 3.0 GHz, 800MHz FSB, 1MB L2 Cache, Hyper Threading Technology
Chaintech nVIDIA GeForce 6600GT Video Card, 128MB DDR3, 128-Bit, TV-Out/DVI, PCI-Express
The total for those main components is $825.77. Of course there is dvdrw, OS, case, PSU and all that other great stuff that you will need.
This was just takent from someone elses post on another forum for a quick idea....(prices taken from
www.newegg.com)
He may also want to think about running Raptor 10k hard drives.
Try to convince him to not use an LCD TV for his main monitor. If he wants TV on his computer just get a TV tuner card and stick in there. The resolution is just not high enough for a good workspace. There plenty of great 17-19 inch LCD's out there. Just make sure they have a 12-16ms response time for working with high motion.
With that being said... I'll add more later gotta go right now.
