I'm looking to buy a new computer and want to get some advice and opinions on motherboards, processors, a power supply, case and ram. It will be a home desktop pc. I'm going to be doing a lot of multi-tasking, running different programs at once like ms word, dreamweaver and statistics programs. I'd like it to be very quick so that I can switch between programs as my current machine is sluggish but it is very old. How much RAM should I be looking at and what type ? As well, what are some above average video cards that you would recommend? As for a power supply, how much juice do I need? I'd like to use my old CD drives & DVD drives but I want to get larger hard drive disks. At this point, I'd like to keep my system under 1000 USD. thanks for your help!
