for the extra $20 to gain another 100watt's id do it. chances are that youll want to upgrade something in the future and youll need the extra power. A little more money spent now sometimes saves a lot of money later.

you may also find that the extra 100 watts may allow you to overclock that bit higher.

750W is more than enough for two 6870s, but whatever you do, you shouldn't get a TX750 or 850.
http://www.newegg.com/Product/Produc...82E16817371025 is a better PSU. And it's currently cheaper, especially after the mail-in rebate.
For the record, 650W is perfect for two 6870s. 850W is completely useless.

A 750w Corsair will be enough. I am running my sig on my TX750 with no problems and that's with GTX 470's in SLI. But, for $20 more I would probably still go with the 850w just to have some more breathing room.

The Antec one posted above is good also, but there is absolutely nothing wrong with the TX750 and 850 PSU's either. They are great PSU's.
