Q: processor speed fsb cache ram speed which is most important please explain 10 points!!!!!!!!!!!
A: You need a well rounded computer. All of these things are important and that is why I build my own. If you buy an off the shelf item, don't get caught up in the cheaper ones. They are not usually very upgradeable and usually not very fast once you load all of your software. It also depends on what kind of multitasking you are going to be doing. I'm in the sign graphics business and I don't like waiting for my computers to refresh large images. It also take a bit of time to rip large files for printing. So, for me, faster is always better. I just upgraded my complete network and I started each build with a high quality motherboard. The better motherboards (over $150) will let you make adjustments to the speed of the processor and ram (overclocking). Example: I bought a Intel E4600 processor (2.4ghz) for $100, put it on a $180 Abit IP35 board with $60 / 4gb of OCZ PC6400 (800mhz) ram. I am running the processor at 3.0ghz and the memory at 1050mhz without any stability issues. I am using windows XP SP3 on that machine with SATA3 drives (faster file transfer). I use Vista on my other machines, but the bells and whistles slow them down. On the processor speed, be sure and get a motherboard that will support overclocking the FSB. You will future proof yourself a bit. My oldest computer is about 18 months old and I was able to update the bios to support 1600mhz FSB. I run that machine with a Q6600 (2.4ghz stock) overclocked to 3.2ghz without any problems. Also, get yourself nice towers that have good airflow and good processor fans/heatsinks. I hope this answers some questions. One more thing...dual core or quad core should be fine. There aren't many apps that actually take advantage of the quad core other than games.
