These cards work great for gaming and daily PC use. After going through the comments, I was shocked with how many people should not be building systems. I mean all these complaints about the cards being 1333mhz and not 1600mhz. These cards are 1600Mhz cards, but you people need to adjust the DRAM settings in the BIOS! Set the timing to 9-9-9-24, the speed to 1600Mhz, and the voltage to 1.5v and ignore whatever computer program that you are using that is telling you..
