Is this computer worth it?

[riva2model64]

you could buy all your parts from newegg.com. they have an excellent reputation and excellent service.

u want dual-core, or quad core? well, they cost the same might as well go with the Q6600. If u want to save cash, get a dual-core processor like e6750.

for motherboard, the ASUS P5K is a fine choice, and is compatible with Intel's upcoming Yorkfield processor because it's a P35 board. If u want to save cash, get the Biostar P35.

atleast 2gb dual-channel if u plan on using vista and playing future games.

the hitachi 7k/t7k hard drives are fast. . 320gb can be had for $70.

for video card, u'll want an 8800 GTS. . whether u should get the 320mb or 640mb version, depends on how high res u'll be playing at.

for power supply, don't get generic. buy from companies like Fortron, Akasa, PC Power & Cooling, etc.

case is subjective. get an ATX case that u think is pretty and that has good airflow.

a system equipped like the above should cost around $1000.
