Shopping for a new (gaming) PC

Now that my lovely fragbox is dead :( I wondered what's the latest out there in terms hardware. My Fragbox 2 cost me about  $2K in Aug 2008 and came with

• nVidia 8800 GTS 512MB PCIe 
• Intel Core 2 duo E8500 - 3.16 GHz 1333FSB
• Crucial 2x2GB DDR2 PC2-6400 800MHz

So, 1.5 yrs later, my nVidia card is about 3-4 tiers down from today's top graphics cards as per this recent article from Tom's Hardware Guide - Graphics Hierarchy Chart.

Similarly, Tom's Hardware Guide - CPU Hierarchy Chart of March 2010, puts my then top of the line CPU as a third tier CPU now.

These are great articles to help understand where technology is now compared to my current gear. I will keep on adding links here while researching.
