Did you really need to come up with a misleading title to get any attention? You realize you're not going to any relevant responses right?

1. The GTX 680 is on par with the 7970 (And considering the horrible drivers AMD provides, Im guessing better)

2. Check your control panel for the card, There might be an adaptive brightness or something turned on? IDK, Last time I owned an ATI card was years ago...

3. Honey! :D

a 7970 is somewhere between GTX670 and GTX680 .

did she kiss back?

According to this chart, the nVidia equivalent to your card would be GTX 590 / GTX 680.

Never experienced the brightness isssue you're talking about so have no idea... (and since I'm at work, no time to google it)

Awk.

The next time I buy a motorboat and kiss it, I'll sure share it with everyone in this site and invent unconventional abbreviations for motorboats.

Lol radeon.

Well played, sir!
I was sure you wanted to say that you kissed your monkey and infected her with aids that way!

You should kiss it while under power. Maybe with some tongue in the cooler.

Good troll is good.

Your brightness problem comes when you use a hdmi cable Even when you set the overscan to 0% in the settings you can still get it in games. U havent a good solution so far in the internet...

Diddely

oh no you kissed your ugly mom!

Well, if it isn't that bitch in the red dress.
