From Cameron: 1) That's shocking. I used a specific case study in sim to compare my two cards. In the same scenario, the 2GB gave me between 19 and 26 fps. The 4GB, on the other hand, shot into the 45-60 range. Of course, this meant I was exhausting my VRAM on the 2GB since the boards and chips are pretty much the same. So long as you're not really exhausting that, your performance between the two should be pretty similar (is SOC higher speed than classified?). 2) For some people, you're right...the 780 is a no brainer. That said, I would hesitate against a 4GB card for my situation (bandwidth means squat if I'm exhausting mem!), and to MOST people it's going to be about bang for buck. With the Titan, 780, and 680 all being out now, the 680 no doubt is a great bang for dollars spent. The performance is fantastic. 1) When I did my test in X-Plane, I first figured out how to configure the rendering settings to fully saturate the 2GB card. Then I applied the same settings to both cards. Out of the box, the SOC is clocked higher not only on the GPU, but the VRAM as well. For certain sceneries, I can run extreme texture resolution with objects and roads maxed out. In others, 2GB won't be enough, but 3GB, as provided on the 780, would get it done...for me. 2) I agree that bang for the buck, the 680 wins. Hands down. But for quite a bit less money than a Titan, the 780 is only about 8% slower. As I mentioned in my previous post, I'll try to find the tests that demonstrate both the fact that a 680 with 4GB is actually choked by memory bandwidth at high screen resolutions and that 3GB VRAM at higher bandwidth would be a better solution.
