Skip 4GB (2x2) to 8GB (2x4) to give a small boost to my PC, allows me to avoid a lot of problems with software such as Photoshop or Sony Vegas (which can be very demanding in RAM) and, of still limited to the rest of my hardware, note the improved performance with some games. My most glaring example is Battlefield 4, which turned very well at 60FPS but with frequent freezes and drops in frame rates: all this disappeared after the upgrade!
Satisfied, I RECOMMENDED!
