Yeah I actually bought my motherboard, RAM, and a 930 for $199 at Micro Center as well. Then they had a price drop on the 950 so I jumped on it.
Funny thing is that when the i7 systems first hit I was all set to get one with a i7-950 for about $550 until Amazon botched my order. After that I put the system on hold until about a year or so later when I decided to revisit the system build and wound up getting a 930, and then later upgrading to the 950 for $229.
Looking back on it now Amazon's screw up was my savings
