is it worth upgrading to? I have the 680i but wonder is it that bigger of a difference besides putting 3 video cards, as soon as I get my Tax Bonus check i’m thinking I might get some new toys, I need your guys opinion on this.

I don’t think it’s worth upgrading as you already have a 680i.So, if you wanna use DDR3 & want to run 3 graphics cards in tri-SLI,then go for it.otherwise it will be a waste of money.
