Unless you never do crossfire and sit on wasted efficiency throughout the PC's life. A 700+W PSU will use an unnecessary amount of power on idle systems.

And if OP one day decides to do CF there will be money for a PSU upgrade as well. Though I don't know anyone who would suggest CF on then outdated midlevel GPUs.

Umm. No..  A PSU does NOT use more power the higher wattage you go...  it USES what is USES..   A 1000W does NOT use more power then a 500W .. Unless the parts of the computer are consuming it..    

Also..  It is NOT just about Crossfire..  even PCWORLD recommends this:

"Most power supplies hit their peak efficiency levels with loads in the range of 40 to 80 percent. Building to about 50 to 60 percent of a PSU's capacity is advisable to achieve maximum efficiency and yet leave room for future expansion."   

So again..   a TDP (total design power) of 350W.. it is RECOMMENDED by pretty much most PC builders that you do 700W or more..
