ASUS, with experience from me, they gave me some nice stuff like a bigger custom fan and copper pipe heatsink, gave me a nice cd wallet, guessing around 20 cd spaces. Gave me some good third party tools, i'm using GamerOSD now instead of FRAPS, and Smart Doctor allows you to overclock the graphics card as well as change voltage settings. It's the only software i have that allows you to modify the voltage settings however you want. GamerOSD allows me to take movies as well, and it isn't limited to 30 seconds like some version of FRAPS. You can change the screenshot picture format too. I thought, or in my opinion i think ASUS & MSI are the best quality producers of video cards. What about HIS, their coolers look the best in my opinion.
TriXX by Sapphire allows voltage adjustments too.
