First question is 1066 worth over 800? It's about a $40 difference but will I see that big of a difference? I'm building this for gaming so I just want to make sure I'm spending my money wisely. I was looking at this Mushkin memory http://www.newegg.com/Product/Product.aspx?Item=N82E16820146785 but at also Crucial's http://www.newegg.com/Product/Product.aspx?Item=N82E16820145197 Any help, opinions, own experience would benefit me greatly. Thanks!
