Incorrect. A second CPU does not 'double the speed' of any machine. Per http://www.devx.com/go-parallel/Article/27399: "With current dual processor arrangements single threaded apps are expected to see a 10% increase in performance whereas multi threaded apps are expected to perform better by at least 40-80% over a uni-processor configuration for a majority of applications." This assumes that the apps that send a thread over to a CPU are able to access the needed data without wait (think disk I/O). > but the slower Frontside Bus (100 MHz vs 133MHz) is the slower > bottleneck, your data will have to squeeze through. Yes, the FSB is a bottleneck, but the difference between 133 and 100 is not that great, nor would be the performance increase. Sure, the RAM bus is 33% faster, but the PCI bus isn't any faster. > another help would be a APG video card with 128 / 256 MB VRAM. more > VRAM is faster. Not always, and generally only when playing 3D games. The card slot is still stuck at the same speed as the original card when upgrading. Any acceleration functions on the video card chipset, or the chipset being faster all together, go more toward speeding up the graphics subsystem than adding more RAM to the video card. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
