Is it possible to share video memory from the computer to the videocard? I've read that it is possible if you have a built-in videocard, the problem is that you wil loose loading speed. Is it also possible with my GTX470?? Cause i'll be running out of memory shortly and I dont want to buy a Tesla ( no money! )hahah

For what I have understood so far, project data have to be stored close to the cuda processing cores to get fast treatment. Using the memory on the motherboard requires a permanent data exchange through slow bus, allowing ridiculous rendering speed...

I hope that more and more gpu brands start to see a real market in gpu rendering and hopefully we will get more capable "cheap" gpu's with lots of ram, now there is not only gamers out there ;)

Yes, but the fact is that there are just few of us, relatively speaking, who need a lot of video RAM. When our numbers grow, prices of ray tracing friendly video cards( those with 4 and 6 GB of ram) should drop considerately.
