Gregg, thanks for the info. It took me a while to digest it and the problem is I still do not understand most of the things in the specification. Can't even find pixel shader units etc. so will have to spend much more time on this.
I should actually get a completely new computer but can unfortunately not afford that right now. I thought I will upgrade in stages. I thought I get a better graphics card (Cuda) and stick it in my present computer hopefully getting some improvement on the performance. I would than at a later stage get a new computer and use this card in it. I now discovered that the new cards are all for PCIe 2.0 x 16. My motherboard has only a PCIe x 16 slot. Will such a card work on such a motherboard (backwards compatible) obviously with reduced performance? At the moment the AVCHD clips play on the timeline but as soon as I add something like a transition, effect, picture in picture, etc playback is jurky. I do not need a super! computer, as long as it will play what I mentioned just now I would be happy (for the moment). The odd more complex part I would render for preview, time is no issue for me. Do you think a better graphics card alone would help at all? I remember many years back I had a 4Gb card and used Premiere 4 (Not CS4) when I changed to Premiere 5 (again not CS5) the timeline would not play at all. I got a 16Mb card and everything work well without any other change to the computer. I hope that it would work as well in this case.
