Because in my country, my 2nd hand X38 board will mean a brand new DFI LanParty DK 790FXB-M2RS, and Intel CPU are hiked around 5-10% more in price compared to AMD counterparts (100 US$ Intel and AMD CPU in USA would mean 110 US$ AMD CPU and 115-120 US$ Intel CPU in Indonesia). I consider 4.0 GHz is almost a lock for Phenom 2 940 on water, my rig is geared for gaming mostly, and if AMD is competitive (especially in price vs performance), i'm inclined to support the underdog.
