AMD's 7000 series cards are awesome.....affordable, powerful, efficient, everything I look for in a video card. I even have two laptops with 7000 mobile chips and they constantly amaze.
I love how their drivers remember unlike resolutions when doing a multi-monitor setup even when one monitor is disabled most the time. I also love being able to play all games at max settings!
My brother just purchased a 7870 and I have to say I am super impressed by the price, the speed, the low noise and heat. Watching him play games at full settings while I am stuck with an old GTX SUCKS.
I have always loved AMD, they always had the best price vs performance deals vs other competitors. Owning the fastest single gpu on the planet would impact my gaming experience greatly. Currently using an old HD4870X2, and it's long due for an upgrade.
