Nvidia's Kepler unveiling essentially amounted to a paper launch, but that doesn't mean the company's GPU partners are sitting around twiddling their collective thumbs. New derivatives of the GeForce GTX 680 graphics card are coming out all the time, the newest ones being a pair of FTW cards from EVGA with overclocked specs, a sturdier design, and even twice the amount of memory.
The 'standard' GeForce GTX 680 FTW, if we can call it that, totes 'just' 2GB of GDDR5 memory on a 256-bit bus. However, EVGA cranked the memory to 6208MHz, a 200MHz overclock that results in more memory bandwidth (198.66GB/s versus 192.2GB/s). EVGA also gave the GPU a bump in clockspeed, increasing the base and boost clocks to 1110MHz and 1176MHz, respectively, up from 1006MHz and 1058MHz.
For people who plan to run ultra high resolutions, particularly when multiple monitors are involved, or for those simply looking for bragging rights, EVGA outed a 4GB version of the FTW edition. This one boasts the same GPU overclock, though the memory drops back down to reference specs. The other difference is that the 4GB card comes with a backplate.
