Upgrade from centrino duo to i5 processor

[ninma]

Hello. I am considering the option of purchasing a computer vs. upgrading my current computer, as my budget is tight. I currently have a computer that has Intel Centrino Duo, but I need a better processor (for Adobe Photoshop CS5). Is it cheaper to upgrade the processor (and other required components) or is it cheaper to just buy a new computer that has i5?
