There is always the option of turning the graphics settings down a tad. Not much image quality is lost, but the performance improves significantly. I personally just use the Geforce experience program to adjust the settings to what it thinks is optimal, then tweak it from there until I have a good balance of eye candy and fps.
No problem means 60fps. When I said "high settings" I didn't mean ultra. If he can't afford another graphics card right now, his 770 will play his games just fine at a bit lower settings until he can afford to upgrade his graphics solution. A great panel that displays nice colors and better resolution looks better than all the bells and whistles in the game turned on IMHO.
