Whatever you do, don't use EVGA cards...

My GTX 660 from EVGA is incapable of automatically adjusting the fan properly according to temperature. Running FFXIV will overheat it every single time. It requires the PrecisionX software from EVGA to control the fan speed. The default package hardware seems adamant to never run the fan at 100% even when the temperature is closing in on 80 degrees Celsius. This is the only reason why they claim it runs quitely. :3

Not to mention the factory overclock makes it unstable in FFXIV. I'm running it now clocked down to its non-overclocked performance, otherwise it will crash the NVidia driver and FFXIV can't recover from a driver crash (game screen will remain blank).
