Ok, I am looking to upgrade my computer but i don't know if it is possible. I have an older pentium 4 processor. Here are my system specs. Windows XP Pentium 4 CPU 1.60 Ghz 512 mb SDRAM Nvidia Geforce 64mb My computer processor can only take SDRAM(maxium 512mb) I want to know if it is possible to upgrade it to a newer or faster processor. One that runs at a high processing rate good for gaming. Around 2.5 to 3 Ghz. Is it possible to take my PC in and they will remove my old one and install a new one? And if they can will my PC be able to accept DDR Ram and over 512mb of RAM? Which is better suited for gaming, a AMD processor or intel pentium 4?
