agreed, s775 had a lot of ho-hum early CPUs and was ultimately defined by its plethora of chipsets, it didn't really matter that the socket lasted forever because it was more than likely you either had to or would want to upgrade the entire motherboard anyway because of a newer and vastly improved chipset. Really the platform as a whole wasn't truly noteworthy until P35, but even then there was eventually X38, P45 and X48 to entice us into continually upgrading our motherboards up until the end of s775
really it just goes to show how amazingly awesome s1366 and X58 has been and has spoiled us. I'm sure there are still plenty of extremely happy campers who decided to pull the trigger and become an early adopter of an i7 920 rig with an X58 motherboard around this time in 2008 and are still more than content with the level of performance they have to this day. Throw in the occasional DDR3 upgrades/expansions and maybe a 5800 series card at the end of 2009 and we're looking at what had to have been one of the most future-resistant platforms of all time.
Socket 939 might have had a similar run if AMD would have never bothered with s754 in the first place.
