It may or it may not
If you have put the new Radeon 5xxx series card in your PC you are buying a overpowered PSU, perhaps a 600W will be more than fine for even 2x5770
If you have 58xx or 5970 in your PC, then yes you will probably wanna go for +700W PSU, as you are planning future upgrades.

Looks PERFECT to me
If you do not play games, stick with the current choosen card
The MotherBoard is one of the best x58's.
And choose this PSU only if you are going to buy a high-end video card
Otherwise, get a 500W-550W. It'll be fine
 
The components you selected are okay. You should not experience any problems.

The Corsair TX750 you selected is an excellent high quality power supply. It can easily power an overclocked system with two video cards operating in Crossfire mode.

The high end, high wattage power supplies such as a 1000 watt unit are designed for systems with three or four video cards. It would be overkill for the components you selected. If you were going to install 3 or 4 video cards, then it would make sense.

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair has a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty.

Can you recommend one? I am so lost on video cards, there are so many i would like one with HDMI under 300.00

thanks!
 
A high quality 700 to 750 watt power supply such as the Corsair TX 750 can easily power a pc system with two video cards. The new ATI Radeon HD 5000 series cards are energy efficient. They actually require less power.

For example, the official ATI recommendation for the new ATI Radeon HD 5770 video card is:

450 watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended.

600 watt or greater power supply with two 75 watt, 6-pin PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

The power recommendations are for an entire pc system.
