Hi guys, I just got a Pentium D 830 PC which has 2 processors at 2.8 Ghz (theoretically). However I keep hearing around a few places that it might not perform as nice as a fast single processor PC. Some say a Pentium 630 at 3Ghz might out perform it for games or some HT applications (like faster compression etc). is this true? I mean, it makes sense. Sure there are 2 processors, great for multi tasking but for a single task it cannot perform it faster than at 2.8 right? My primary use will be HT more than gaming. Also some small editing and compression of video. Mostly watching HD trailers and watching DVDs upscaled. Am I better off with a really fast single processor with Hyperthreading? Also I went from a super old Pentium 3 500 to this and to be honest I cannot say I see a HUGE difference in speed. old one had 128Mb RAM Vs 1Gb on this one. Shouldn't the difference be night and day? How can I test the PC to make sure it is not defective or something?
