Vista 64 bit will recognize no more than 4 GB of ram, or I would have more. Only way I can increase performance now is to add a better chip and that will result in such a small WinPerIndex I cannot justify the expense.
Incorrect. Vista 32bit will not recognize more than 4GB, 64bit WILL recognize more than that unless it is a motherboard or chipset limitation. I am assuming though that it is DDR2 Ram which is last generation and now really expensive to get, so I would agree that Windows 7 would be your best way to upgrade your performance as of now.
@Mini Motors... I think you forgot an i for your processor. Should be a Core i3 :biggrin:

Edit: On the RAM issue it looks like it is dependent on the motherboard you have.

Read post from jsktx half way down the page. So again, Vista 64bit isn't the issue, it would be your chipset. If you have 4 slots, I think you just need to have your bios updated and you can have up to 8GB, but DDR2 is still too expensive IMO.
