Trying To get a nice build

[Hellsadvocate]

I've been playing with computer hardware for a while, and i'm a bit new at this.
This is my current system:
Q6600
P4M890T-M2 motherboard
2 GB DDR1 533 Mhz
800W Ultra PSU
8800GTS 640MB

(This configuration doesn't work because the ECS motherboard doesn't support more than the dual core processors, so it just hangs after POST even though it recognizes the CPU if anyone knows if it is indeed my motherboard's incompatibility thats causing this problem please let me know)

My new configuration is as such:

2 GB DDR3-1333mhz OCZ
Asus Deluxe P5E3
(This is a backordered so I expect it near the end of march)Intel Q9450
And my same old 8800GTS 640MB

My motherboard and memory are on their way, so my new setup will be all of that, with a Q6600 which is just a 1066FSB, which is okay for my RAM I guess just won't get the performance I need. My question is, how long will this build last in terms of practicality? what kind of performance can I expect? reviews for this stuff are up but most websites are using QX6750 or something as the processor.

Thanks for the help guys, i'm new here and it's my idea that everyone here knows a shitton about stuff like this. Any help would be appreciated as i've had a ton of problems in the past with my setups.

In terms of practicality? It depends on what kind of user you are. What types of software you use, what games you play and at what resolution...etc.

performance should be great...again it depends on what you do. (this applies a lot with gaming and what resolution you run.)

also if you OC the CPU then it should in theory be practical for a longer time.

Gaming, my highest res. to be honest has always been 1024x1280 with everything maxed out (including AA) my main games are RTS games, Sup Com to be honest which runs hard on any of the rigs I have. I'll also be using this comp for Illustrator, Photoshop, Vectorworks, Autocad, and the ilk.
