Changing CPU requires a start from scratch

[schwubdiwub]

My Hack works fine now. The only thing: i have the wrong CPU. It's a Core i5 3450 with the HD2500 but i will buy a 3570k with the HD4000 to get the full GPU support.
Meanwhile (shipping will take it's time) I want to work seriously with my Hackintosh, installing Apps, moving Files from my old PC to it...
Do I have to start from scratch if I change the CPU, or is the system smart enough to use and recognize it without problems?

there should be NO problems with that CPU change... even the HD4000 is fully supported. but as always having a backup in case something goes sideways is always the best plan.
