PSU for Radeon HD 4870 X2 ?

[kbohannon]

As what title says, i am building a computer and would want to know what the best power supply to use would be using a single Radeon HD 4870x2 possibly over clocked with ASUS Rampage II Extreme motherboard, Intel Core i7 Extreme 965 processor, and corsair dominator DDR3 6gb ram, not sure on harddrive yet.
Thanks for your help.

750 watt

850 watt This is for head room.
1000 watt If you want to Crossfire later and are going to overclock the rest of your sytem. This would be a great option just in case you upgrade or add more parts later. This will give you room to overclock all of your parts and add another card.

your 750w and 850w are the same link to the 750w...
