i have the 680 classified, and it runs quiet and cool, from what ive heard amd cars run hotter and louder, but i never had one so i cant say for sure, but im very happy with the 680 im sure someone with a 7970 or 7870 will share there personal experience with the card
The 7950s are great, but if you are on a smaller budget, a 7870 XT is great. Ideally, a 680 or 7970 would be best, with the cards switching out as number 1 as drivers update and change, but for a budget, 7950s are fantastic. More is better :)
I always buy the top of the line single GPU, and it almost always out lasts it's sell by date...
Still rocking a GTX 480 and smashing every game out there on top graphics settings.
At one point, 1.5GB was called overkill....... the same is with 3GB right now, but that is true, but something will come out demanding more Vram in the future..
