I don't overclock, I don't play a lot of games, I just like a responsive, reliable system.
I will likly buy...
A Conroe E6400, maybe a 6600 if I have a few extra dollars when I buy
Likely an Intel 975 motherboard, or the ASUS p5W DH, used a zillion motherboards from each firm over the years, both have done me well. - solid, stable, rarely any grief.
Likley 2 gigs of ram - DDR2-667 works just fine, the extra money for DDR2-800 at low latency just doesn't buy me enough speed to be worth it.
I have a 74 gig raptor I will recycle from the existing rig, and likely toss in a 300+/- gig or so Seagate or WD hard drive for extra storage.
A generic DVD burner for 35 bucks or so, still want a floppy so add $11
I don't have a TV, but I do have TWO Dell FP2405 24 inch LCDS, so I'll buy a midrange+ ATI "All in wonder" card to get TV/VCR functionality - an X1800 XL looks about right as it has twin DVI outputs for the Dells. - I'll buy a mid pack audigy sound card to drive my AWESOME (they truly are amazing) Klipsch 5.1 ultra speakers.
Get a new case, probably an Antec with a Power supply included - A nice quiet Sonata for $105 or so looks about right. I don'r do SLI/Crossfire, don't have a killer GPU, and Conroe sips power, so something in the 400 watt PSU range is plenty...
Thats about it...
New stuff to buy..
Conroe $250-350 (depends on model)
Motherboard $250
Ram $200
DVD + Floppy $50
HD $ 100
Case $110
Sound card $ 100
Vid Card $300
About a $1300 +/- and I am done, and happy for two more years
