Great to see nVidia jumping back into the game and forcing AMD to lower its prices accordingly. I was shocked to see the card actually available at the MSRP of $500 on launch day. I guess we'll see how long that lasts.
For everyone suggesting that nVidia will release another true "flagship" beyond the 680, I think you are spot on, IF AMD gives them a reason to. There's no reason to push it at the moment as they already hold the crown. If, on the other hand, AMD goes out and makes a 7980, or 79070 SE card with higher clocks (more like what the 7970 can achieve when properly overclocked), I definitely see nVidia stepping their game up a bit.
Either way, it's awesome to see both AMD and now nVidia taking power consumption into consideration. I'm tired of my computer room feeling like a toaster after an all nighter.
