"This is a
reference card,
without voltage tweaking your limit will roughly be
800~825 MHz on the core (1600~1700 on the shader processors). Memory can be clocked at 4400~4500 MHz (effective)."

Keep the gtx570 card at or below the 1.1 voltage and there fine.
Just because some morons were bios flashing and were giving them too much volts , that makes them shoddy overclockers? No way!
They have a normal failure rate, just like any other card.
Edit: oh, and one more thing, the Toxic card was loud when overclocking/unlocking compared to a gtx570 @ stock.
Read the review...........
"The air that the fan was pushing became audible at 48% fan speeds. At 55% the motor in the fan became audible over the systems normal operating hum"
"After overclocked, fans were much more noticeable, but
we had them set to 50% or higher at all times, which was necessary to match the performance of a Radeon HD 6970"
So the Toxic card cost as much as a gtx570, needs to be overclocked and unlocked to match its performance @ 1080p, uses about the same power as a gtx570, and will be louder because of the overclock.
And would lose in 90% of benchmarks @ 1080p if you just overclocked the 269$ gtx570 without voltage.
I'm impressed!
