The issues are not necessarily with X-Plane.  It is a driver issue, specifically OpenGL implementation.

 

The Nvidia drivers have been much better than ATI's for Windows machines.  So, for X-Plane, you would be more satisfied with the performance of the GTX 680.

nVidia has far better drivers in general, and support. I would go for the GTX680, AMD produces good cards on a technical level, but they lack support and compatibility as far as I know.

... only for OpenGL, which is what X-Plane uses.

 

For DirectX applications, AMD is quite strong.

I have been using AMD for years and have seen no problem with Xplane  . My current Card is a Gigabyte 7870 OC . They always say that NVidia does OpenGL better but I have never had a problem . May be someone can let me know what I am Missing as far as OpenGL is concerned . As far as I'm concerned AMD works just fine with Xplane .

I am not suggesting that AMD has a "problem" at all, as I have also been using AMD GPUs since early version 8 of X-Plane.  What has been stated often both here and at the .Org is that Nvidia OpenGL driver performance has been proven to be better on Windows machines, and for that reason my next flightsim rig will have an Nvidia GPU.

 

If the performance of your AMD GPU is meeting your expectations, then by all means, enjoy it!    :)

Decided to go with amd 7970 do to the fact that A. It's $100 dollors cheaper B. I own a render farm that now has a gtx 560 in it so as long as the card works fine in solid view mode I Don't care about rendering as Nvidia still handles that C. i Currently have a 560 I will see a boost in performance bad drivers or not

Also I should mention that it currently is in the mail so good luck changing my mind

Here's a link to the actual card i bought

Also i already have plans for my 550 TI and the games are heading to ebay

Ok little update, Bad news: I have recieved to 7970's and both were DOA :( i have since requested a refund and am going to buy a nvida based card

Good news: Turns out newegg lists their game coupons as seperate items when you buy your video card so neweg gave me $180 for my inconveniences :) also just learned that cycles doesn't support gpu rendering with amd cards so I really dodged a bullet by recieving 2 DOA cards

Unrelated: is it normal to receive two doa cards in a row from Gigabyte?

If you were to compare the reviews of equivalently clocked 670s given the same amount of VRAM, you'll find the results to be within typical sampling error margins.  There isn't a significant difference.

 

Generally the support from EVGA and ASUS is considered pretty good.  Just find the best deal you can.
