depende na sa budget nmo gyud bro... ug sa monitor resolution na gamiton ug sa planned "Game Presets" ug unsa na game... mao ni sila ang mga dictate sa GPU na atoang need... and not the "Nice to have"...
that GTX 780 is more then enough... for a single monitor at 1080p and all settings to be maxed out... except for some... maybe, 1 or 2... i can't comment on it since i don't have any actual hands-on experience on the Titan Light (GTX 780)...
