Pros: ULTRA Powerful, Efficient, Large Ram, Great heat management, top of the line
if you only have 1K to spend on a GPU you may like the 690 better, HOWEVER, that is a dual GPU card It essentially runs in SLI mode, so with it comes all the SLI problems with games and drivers, that plague most other SLI people.
for the FASTEST, BIGGEST, BEFFIEST card the GTX TITAN is THE BEST.
Has more ram than the 690 meaning larger resolutions are easier, as well as multiple monitors, a single titan can do so much.
the 690 is only capable of 2 way SLI (4way since the cards are dual gpu) with two physical cards. the titan can do upto QUAD SLI
get three titans and nothing compares other than quad titans
the EVGA software is nice.
Fan control and temp target are really nice, your clock speed are only limited by how much fear you have and the cooling, MAX fan speed is rarely used in max settings on Bioshock infinite at max, so doubt sound is an issue, however max out the fan and start cranking for some serious power.
I am SO glad I got this card.
