I have an older Pentium IV myself, with 1GB RAM, from my experience, it's not so much about memory but about the processor. Linux is very respectful about RAM memory usage and besides you can always create a swap partition, so in the end it comes down to the processing power of your PC. If you have at least a dual-core, Ubuntu will work just fine, as long as you don't open too much applications or webpages filled with flash advertisements and banners at same time and as other people said, change to Unity 2D. If you want to be really sure to have a system running smoothly, I strongly recommend Lubuntu, based on Ubuntu 12.04 with lightweight LXDE interface, however it is not LTS (Long term Support), meaning that it will not be supported when 12.10 version arrives. Try Ubuntu first in a Live-USB environment and then check if your system runs fine with it.
Yes, but will be a little slow.
There are many solutions to speed up the system, though:
swap
partition (during the installation process).That's all comes to my mind right now.
I run 12.04 on a laptop with only 1GB ram and it runs okay. I had to use Unity2d because Unity3d was really sluggish. Using another window manager other than Unity would probably make it snappier.
