Ok, so, I've just recently gotten my computer shipped from home to me and its pretty old, so I want to upgrade it with some better hardware. I wanted to start first and for most with my Processor, RAM, and Graphics Card. My motherboard is: MSI K7N2-L ATX NFORCE2 AGP8X DDR 5PCI ATA133 I currently have in my machine: -Processor: AMD ATHLON XP 3000+ 512K 333FSB BARTON -RAM: CORSAIR PC3000 CAS2 512MB DDR CMX512-3000C2PT -Graphics Card: ATI RADEON 9700 PRO I don't know an extreme amount about individual parts, but I do know basic stuff here and there to get by. I wanted to get the best with my money, but I want to go as fast and high quality as I can with the parts. Can you guys run the basics by me with how I should go about choosing a new Processor, RAM, and Graphics Card for my machine? What should I look for compatibility wise? How do I know what's what? etc THANKYOU!
