So after impressing my office with Lumion my boss has decided to purchase a better [suited] graphics card for my computer. I'm currently running a Quadro 4000 on my computer and it's been, to say the least, abysmal. I work in Build Mode at 1-3 FPS, and I typically render a scene at around 40-50 seconds/frame. I used my Radeon HD 5770 at home to get slightly better render times, but it still took around 40 seconds to render one frame. For a three minute video that meant I needed about 60 hours available to render. Complicating things, considering I'm still learning the software, any mistakes resulted in often 7-8 hours of lost time re-rendering.
I'm considering buying the GTX 670 after careful consideration. The 690 is out of my price range ($300-$400), and the 680 is slightly out of that range as well. So here are my questions:
1. Is the GTX 670 a good card suited for Lumion? Is the 680 a significantly better card than the 670 and worth the extra money? Like I said, I'd like to stay below $400.
2. How much improvement over my Quadro 4000 should I expect? I'd like to see render times significantly shrink as well as improved Build Mode performance. If I'm only getting marginal improvements I don't think it's worth the investment.
3. Can I keep my Quadro 4000 in my computer with the new card? The Quadro still performs great, especially with Revit and 3D Studio Max. Unless the GTX card is equal in performance with those applications I'd hate to just improve performance with one software and sacrifice in another.
