Stick with Q9000 DV7-2040US or Upgrade?

Hi Everyone;

I just recently bought a DV7-2040US at the store, it was "cheap" on-sale for $1160.00, I still have a return option anyway; so if I find anything out I dislike I can still just take it back and get my cash money back, Haven't opened it: a good link to check this system out is:

It comes default with a Q9000, Intel Core 2 Quad Q9000 2.0 GHz Processor,
My thoughts were: basic system is good? Buy better core to replace this one? What to replace with? QX9??? or Maybe step down to a High Clock Dual Core Processor?

Any thoughts?

Or is this a system to just return, get my money back, and buy something else alltogether? Budget $2000.00ish. I am mobile but always use an outlet; Home-Office-Home, battery life not too important would like 1.5 hours, Will play games Crysis, World at War, EVE, Empire: Total War, Will also be using CS4 Master On this System as my new Personal Business Computer so I need to be able to effectively use Photoshop, Illustrator, Flash, Dreamweaver, Fireworks, Etc... I also would like to be able to Dual Boot this System with Vista Home Premium (its what i have already), and Linux Variant. Screen size: 17" and up Preferred, Decent Screen at least, HDMI Output? Wireless N, DVD Superdrive if not BLU-Ray...Sorry for all the details, but this way you know what I need and would like in my next Laptop.

Thanks for all your help:
