If you get less than a Q6600, AMD might be the better choice, as you can get a MoBo that will accept the next couple of generation of CPUs. The Q6600 is priced less than comperable AMD, and AMD doesn't compare above the Q6600. you can get a 3.0 ghz dualcore AMD 5800+ for $100. thats probably the processor I'd buy if I were in the market for a dual core. make sure you get a mobo with HyperTransport3, to get the most out of future CPUs, such as 780g, 8200 of 7900fx
don't buy a DDR3 system, stick with DDR2. 4 gigs of DDR2 goes for less than $100
just pick up a good 500+ gig HDD, and use the external to backup your music files. anything with a 32mb cache should be pretty quick.
I got a 750 gig 7200.11 a few months back for $130. I assume they are still about the same price, maybe cheaper. its not that much more for big drives.
I'd get Vista64 home premium.
based on the age of our build, I assume you have a CRT. you realy should consider getting a 22" LCD. after getting a 17" LCD a few years back, I'd never consider a CRT again. the picture is better and more vibrant, and much less eyestrain.
figure $80-100 for each of these: CPU, MoBo, HDD, Memory, PSU, OS,
add in $180for a 4850.
youre looking at about $700
