Hard to say what the gaming experience will be like. When you ran the Intel Driver Update Utility, what did it tell you about your video/graphics?
Also, and again this is just my personal opinion, I would avoid any of those driver update websites. It is always best to go to the manufacturer of your PC/Laptop, or here as you have done, to get the proper drivers.
For more help, tell us what the model of your PC/Laptop is, and if you use onboard graphics or have an add-on graphics adapter.
