Overclocking
Teasing out extra frequency by increasing core voltage to 1.087V, we hit a solid 985MHz GPU and 4,400MHz memory. While a decent bump over the already-overclocked Twin Frozr II speeds, the final frequencies are a little lower than the ASUS TOP's.
Still, if you like on-the-edge gaming, here's how the extra horsepower helps in Aliens vs. Predator and Just Cause 2.
It's horses for courses and GPUs for benchmarks.
