Note about optimization from owner about SLI game optimization. The unit ships with only one graphics card active. I can imagine lots of people never even knowing this and just thinking that only one side of the unit vents hot air.
As I posted last night, I had an issue with this unit actually using both GPU's in SLI. This has been resolved. When your Y500 arrives, you will need to download the NVIDIA Experience Beta [geforce.com]
. Using this tool to "Optimize" your game settings will definitely enable SLI for SLI enabled games that you own. I've tested this thing and can confirm GPU load on both cards of 90%+ was achieved in DOTA 2 and the unit began to vent hot air out of the exhaust points of both cards.
