Suggestions? > I don't know about the video editing, but transcode (the backend DVDRip uses) can use multiple cores to do the video encoding. On top of that there's always audio encoding as well. That means two cores gives you a ~2x speedup (not quite 2x, as audio isn't parallelised). Comparing the prices of dual core CPUs with ones twice the speed it quickly becomes apparent which the better option for that application is. In addition the faster processor makes more demands on the rest of your hardware: you may need faster memory and a more expensive motherboard for it. -- imalone -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
