They really DON'T drop prices very much. You just need to find a good sale. You can see that Ivy Bridge is just a tad cheaper than Haswell, but Sandy Bridge are still about the same price, and some examples like the 2500k are even more expensive.
ugh.... even at micro center (why are they cheaper than newegg and tiger??) its only 15 bucks off everyone else, once you consider tax..... when is AMD's steamroller actually going to splash the market? q1 next year?
