Which would be a better option GTX 680 or Two HD7850 in Crossfire??
Thanks for your help
Depends if you Get a SLI Motherboard The 680 is by far the best option amy be weaker at the start but you can add a extra card later and 2 680 will own the 7850. even if you dont i would strongly recommend getting a better ati card as the saysing goes always buy the best single card you can afford.
I don't think getting the single best card you can afford is always the best option. If your budget is $250 or less, sure get the fastest single card you can afford. If your budget is $300 or more, and if you plan appropriately, dual-card setups are usually more powerful. Planning on adding a second card later rarely works out. By the time you're willing/able to upgrade your card is out of production, there are faster cards out already, or both. Then we're back at "buy the fastest single card you can afford".
That being said, I'd recommend 2x7850 over 1x680. Crossfire drivers are a non-issue now, and you'll get more performance for less money.
