I notice that the z68 I could have purchased for 50 dollars more offers things such as SSD caching, on cpu video & "Intel Smart Response". I purchased a P67 mobo (Canada Computers | Motherboards | Asus SABERTOOTH P67 (Rev. 3.0) Socket 1155 Intel P67 Chipset Dual Channel DDR3 1800/1866/1600/1333/1066MHz 2x PCI Express 2.0 x16 3x PCI Express 2.0 x1 Slots 8-Channel HD Audio Dual GigaLAN 2x SATA 6Gb/s+4x SATA 3Gb/) for my first build but after doing some reading (I know.. I should have done the reading first.. but Sabertooth just sounds so awesome ) am beginning to think I could get a bit more on the z68. What are these features? Are they just fancy acronyms for a true enthusiast?
