>> ASUS HD 5870 Matrix Platinum 2 GB Review
The ASUS HD 5870 Matrix Platinum is clearly engineered for maximum overclocking. It has 2 GB of fast GDDR5 memory and features software voltage control for three voltages. One unique feature is that the ASUS iTracker 2 sofware can put your changed settings into the BIOS so you won't have to worry about OC software anymore.
