It really does make you think though... Back in the late 90's and early 2000s, a 10yrs old system, let's say a Pentium II would have been seriously outdated by 2007 or 2008. Heck, I already had a PCIe Radeon X1550 in 2007 & used SATA hard drive! Not to mention the 64-bit capable processor, with first gens of Dual Core chips already out there, on the market.
On the other hand, Q6600 will now be 10yrs old, and it can still compete with current systems. In fact, the only two upgrades I've done to it were adding GTX760 (instead of original 8800GT) and adding additional 4GB of DDR2... So yeah, it really makes you think just how much technological evolution slowed down, to the point where it's depressing to watch and/or talk about it...
