This is probably the best philosophy regarding RAM but there are a few points for consideration.
Make sure the OS your new computer is running is a 64-bit OS if you go with more than 4GB of RAM. 32-bit versions of Windows can't address more than about 3.8GB of RAM.
My personal machine has 16GB of RAM. I find it nearly impossible to use that much RAM UNLESS I run multiple VMs (Virtual Machines). A VM is a software version of another computer running as a program on your system.
Adding more RAM to your computer does not magically speed it up in any way unless your system is starved for RAM in the first place. Most users rarely put 4GB of RAM to full use.
