Check the benchmarks and you will see there not much different and while the 920 does out perform the 860, your also going to spend more money on the hardware. The mobos and are more expensive and of course a tripple channel kit is going to be more then a dual channel. I am just going to run the RAID 0 then use one of my current hard drives, or a small new HDD for back ups. I am only getting one apevia and its simply going to be used for looks rather then airflow. Well it will be used for air flow but not going to make a difference with my case set up. I have 4 GB in there, its just they dont make that set in green and they(crucial) confirmed I can run these sticks in dual channel just fine. I realize that but the speeds should be sufficient. Yep, I want the green as I may add a black light in my case. Like I said, this is an upgrade I have a 22 inch Dell 2208 WFP monitor and a Mozart TX case so Im just fine there. Also have a Saitek Cyborg Keyboard and Razer Copperhead mouse.
