Thanks for your replies, guys.
@dibya_kol Sorry, I forgot to mention that I game mostly at 1920x1080, sometimes at 2560x1600, depending on whether I'm at home or at work.
@topgear Very nice, but that's a three-slotter card. Zotac is using a 680 PCB on their AMP! edition, and they slapped a huge cooler on top of it.
@Arnab I've come across the Asus 680 DC2 a lot of times. I'm very tempted to buy it but, like the Zotac AMP!, it's a three-slotter card. Not very convenient for me, since I'm planning to run SLI and add additional PCI cards later on.
I think I might have to wait one more week before more of these hit our market.
