DDR3: Size vs Speed

[kristmace]

With DDR3 prices being so cheap I'm thinking about upgrading to 8GB from 4GB. My PC is mainly used for gaming, but I do the ocassional bit of content creation stuff.

My current RAM is 4GB G.Skill Ripjaw which runs at 2100Mhz. Would 8GB of normal 1600mhz RAM actually perform worse because it's slower?

So the speed isnt really an issue. Thanks.

Whether I'd actually use the extra 4GB, thats the real question.
