It doesnt matter if the CPU is 64 Bit or not. It doesnt matter if it is 3.4GHz or not. Having 512MB of RAM will cause you to go slow. Period end of story.
You need to read up and understand how RAM works in conjunction with the CPU to make your system work and how having more RAM with a good CPU will make your system fast.
The RAM is the gateway. The information you do on the desktop is sent to the RAM, from there sent to the CPU for processing. After that it is sent back to the RAM and then back to you.
So now tell me do you think that using a fast CPU with bare minimal RAM is going to allow your system to work fast or slow?
