availability of all 32nm chips will be very low as TSMC yields currently are quite low and hence prices in the start will be quite high
i suggest the op to do this and get the following config
1)2600k
2)z68 based asus vpro
3)8gb ram
4)a good case of op's choice
5)a good cooler, again of op's choice
6)a proper 850w psu by either seasonic or corsair
7)the monitors- i suggest the dell st22 series
8)a 120gb boot ssd
the GPU and HDD parts should wait up till 1q 2012 as prices will be a bit better and also the $ will stabilize, bringing the overall prices down again
