I recently got a new job that has given me a little bit more cash than I used to have, so I thought "what to buy" ? Perhaps it's time to update my venerable PC which has been with me for some amount of time. 
I'm pretty set on this idea and have been doing a tonne of research.   
To fill you all in, here's what I'm going to be moving from:  Pentium IV 2.6GHz 
       2 GBts of RAM 
80GB hard drive! 
7800GS AGP graphics card 
 
So that's the important stuff.  I know what you're thinking, "holy crap, that shit is archaic!" and you're right.  That said though, it's done me proud pretty much up until fairly recently.  I was able to play STALKER with reasonable settings and FSX. 
So, after loads of research and swaying, here's what the new system will be (I think):  Phenom II X4 BE  (possibly X6 if the price is right) 
   80GB Solid state drive & 1TB storage drive 
           4GB DDR3 RAM 
    ATI 5850 
So, those are the important parts.  Windows 7 as well.  It's pretty exciting as I know that I'm going to see such a phenomenal speed boost and gain.  PCI express/USB 3/ SATA 2/3 all didn't even exist when I built that old system.  Games I'm super looking forward to are Call of pripyat, Anno 1404, ArmA 2, Empire:Total War, Dawn of War 2 and a few others. 
 
Let me know what you think of the system and any other recommendations you guys have.
