CO2 PPM ..2500ppm Co2 today? less than 400ppm. I'm quite sure the earth isn't going to stop it's natural cycles because of our pathetic existence. Especially not because of CO2, which is a common byproduct of most lifeforms on planet. In the grand scheme of things we are truly insignificant. any extra we put out just means the earth can support more plant life. I see this as an opportunistic piece to point at and convince people of the new terrorism. I'd be all for a cleaner environment and conserving resources if it weren't wrapped in sensationalist tyrannical agendas out to control the population.

Why don't you just buy a 5770 and crossfire it with your 4 series. They'll work together that way. But you will have to buy a bigger power supply. If you have the money, I'd get the 5870 or 5970.

Apparently the president is dictating that America should sign a treaty that directly violates the constitution. Checks and balances would normally kick in....but no. There is something fundamentally wrong with our society(US) at the moment. I just hope we snap out of it before we go over the falls. I fear I might already feel that moment when you adjust to the sensation of gravity fading away.
