$11 for a new GPU! Nothing to complain about that, haha! Glad you're happy with the purchase :-)
Interestingly, our friends over at Legit Reviews just did a comparo between a Q6600 and 4770K to show the differences in upgrading from one generation to like... five later? Some of the results are pretty shocking: http://www.legitreviews.com/article/2247/1/
It's REALLY cool to hear that your C2Q machine handles 1080p fine for those higher-end games though. That really was a fantastic Intel generation.
