I want to have a better overall desktop computer performance. But I'm not going to buy a new CPU or motherboard. Perhaps I will buy additional hard disk for storage, additional memory, or applying any hardware technology supported by my current CPU / motherboard, as well as installing any software applications for this purpose. Do any of you know any websites/URLs that contains any information on this matter? By the way, my computer has Intel Pentium 4 2.8 GHz and the motherboard is ASRock P4VM800 ( http://www.asrock.com/mb/overview.asp?Model=P4VM800&s=478 ). Any help is greatly appreciated!
