Well the Asus is overclocked higher and looks like it may have a better cooler. Either way, both cards will pretty much max out any game currently out at 1080P and max out most games up to 2560x1600.
You're choosing between a .44 Magnum and .50 Cal. The .50 Cal is more powerful, but both kill in one shot (assuming you play at 1080P).
Decide which game you want/like or can sell if it comes as a box. I personally think the extra memory of the EVGA FTW will be more useful at higher resolutions while the clocks of the Asus will be better for higher settings and more demanding games.
