... I keep telling people to just hold on on the Bulldozers until a price drop is announced if they want to build a gaming computer, because its architecture isn't optimized for single-threaded applications... furthermore modern games are more dependent on the GPU than the CPU...

The i5-2500K and i7-2600K are basically the juggernauts here. They have been since they were released, in fact. No actually the Nehalem processors still outrun the 2600K (i7 980X, 990X, 995X), but their power efficiency is just... bad, and LGA 1366 is a dead end in terms of upgrading.

The XHair Formula V runs at $229: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131735
The FX-8150 is $249.99: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103960

EVGA Z68 FTW 160-SB-E689-KR LGA 1155 Intel Z68 SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard is $244.99
