The mobo has ram speeds of 2133*(OC)/ which I have never went beyond the stock speeds before. Can the mobo over clock the ram to the right voltage or would I have to doit by going into the Bios and changing the voltage?
Also what would be the pros and cons of doing this OC?
RAM overclocking doesn't get you a lot of extra performance, and it's not worth the money that you have to spend on sticks rated for the higher speeds. This isn't like CPU overclocking, where any unlocked processor can be expected to do quite a bit more than it's rated for and where performance in some mainstream applications scales with clock speed. Just get a good 1600mhz set and save yourself some money.
Also, that mobo's more expensive than you need. Get something like an ASRock Z77 Extreme4 and save more money. Tom's recently-approved boards in that price range: http://www.tomshardware.com/reviews/z77-express-ivy-bri...
With the extra money that you'll have from not wasting money on fast RAM and an expensive motherboard, you should be able to fit a 670 into your budget, and you can go ahead with your build whenever you like
Money isnt an issue for me really and my budget is about $1600 for a computer. Yes I could get a 670 or 680 but what I was trying to do was a black/blue type theme for my computer. Black case blue LEDs and a black/blue mobo with black/blue ram. This is what I first was going to get for my rig.
But I figured why not get something with a little more kick then 1600mhz? I did read that the 660ti is going to be a pretty good card aswell. Im not looking for some crazy rig because I plan on getting an i5 Ivy aswell. I just want a system that will play games pretty damn well but not perfect!

You can if you want, but it's definitely a waste of money for gaming (or pretty much anything else), as kajabla said. If you want big RAM related bench scores or you're running a RAM disk (which you'll need more than 8GB to do well anyway), then go right ahead, but there's no reason at all to do it otherwise.
