There was a thread running about a month ago treating this very topic. You probably should have a look through the archives just to see what we went over then. > I have looked at the option of running > dual processors (intel and AMD), and it appears (allegedly) that gains made > by the use of dual processors can be overcome by the purchase of a single > processor running at 20% higher core bus speed. Based on what sort of usage? In an application that is multi-threaded I would doubt very much that statement. If it was just a single threaded app then I could understand because that 20% is probably just the OS overheads being shifted off to the 2nd CPU. > I am also shying away from > instituting SCSI as I don't 'think' performance gain from synchronous bus > would justify cost - my hard drives use different channels and I am pretty > careful where I put and run things from, hopefully avoiding asynchronous > pitfalls. Not really. The advantage of Scsi is that the control functions are shifted from the CPU to an on-card controller. The other advantage is that SCSI reorganises requests to make things more efficient. So, even when you only load textures from one HD and application data from another, you'll still run into performance issues. -- Justin Couch http://www.vlc.com.au/~justin/ Freelance Java Consultant http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Look through the lens, and the light breaks down into many lights.
