I think an obvious test, would be to look how much your disk light comes on with your current system when it is processing your large problems.
You don't say whether you are using the 64-bit version of W8. If you are not, you should switch to that. Mathematica will then need to be re-installed (because the installation disk actually contains both the 32-bit and 64-bit code, selected according to the OS), but nothing else would be required. Indeed your 12 GB will not be contributing much more than 4 GB would without the 64-bit OS.
