You will most certainly experience the benefits. There again it depends on what you do with it. If you were to edit video eg you will see the difference but for word processing there will be very noticeable improvement. Why not buy a m/b w/o onboard graphics. Its much cheaper and you can put the savings towards a good graphics card. Gigabyte is a good choice in my experience.Also try to take advantage of the dual channel capability from the start when buying memory. Go for it, you'll not regret it.
