suggestions for Quad Core system

My current components (may change as needed):

Intel Core 2 Quad Extreme QX6700
Viewsonic 22" Wide DVD LCD 5ms
Antec Nine Hundred ATX Case
SAMSUNG|SH-S182M/BEBN BK
ZALMAN CNPS 9500 LED
Corsair TWIN2X2048-6400
Seagate Barracuda 7200.10 320GB/S
VGA XFX 7600GT 256M PVT73GUGD3 R
Asus P5W-DH Deluxe LGA775
Antec Neo HE 550W Power Supply

Estimated cost is $1300 with CPU included.
I'm not a hard core gamer.

This is my first time to build a computer system, all suggestions/advice would be greatly appreciated. Thanks.

change your motherboard to the Asus P5B Deluxe

and actually there is no possible way you spec'ed all that out and its total cost came to $1300 with the cpu included.

the cpu alone in that group is $999, and i'm not sure what your kind of rig this is going to be but if your not a gamer and not an enthusiast(since this is your first build) i don't see why your getting that expensive of a cpu.

Any Core 2 Duo would give you the same benefits and same performance as the Core 2 Quad due to the fact that not very many multithreaded programs out there. Regardless of whether you think the Core 2 Quad is more future proof by the time software is written for 4 cores these things will be much cheaper and other options will be available.

Why don't you tell us what this rig is actually for so we can suite it to your needs better

Not even in your wetest dreams.

Dead link.

Not anymore.

5-star

Sorry for the confusing I've made earlier, just ignore the price of the CPU (1000-1000 for me). I just put together the entire system just as listed above. It ran perfectly so far after updating to the newest version of bios.

I ran the 3DMark06 free version, here the results if you guys want to check it out....

just in case any one cares, that computer comes out to about $2800
