I'm trading in my MSI 670 PE for EVGA 670 reference cards because I want to water cool them but MSI's version doesn't have a full water block available for their model. I just found out that the reference EVGA 670 has a smaller PCB compared to the FTW. Does that make any difference in regards to overclocking? Should I just continue with the trade or just sell the card and buy a 670 FTW instead for OC and Water Cooling?
Don't bet too much on overclocking, since Kepler is voltage locked you are very limited in that aspect. The FTW is probably binned better and has a more stable power delivery thanks to its 680 PCB, but, you could still be unlucky and get a card that craps out after a 10Mhz boost, on the same note theres a chance you could get a great reference card. The joys of the silicone lottery I suppose.
Idk about you but I love my GTX670 FTW from evga. WAY STABLE OC's Plus EVGA's K BOOST for Voltage makes it rock!! Also the fact that the 670 ftw uses the 680 pcb makes it easier to find watercooling solutions too. +105 pt +135 gpu c +240 mem c = 1332mhz core / 1174 mv))<<my sets in precision x // I plan on getting a second one and throwing it SLI!!
