Hi guys, I have a P55 setup which is running with an i5 750 @ 3.8GHz. I have recently obtained an i7 870 which i'm going to swap in. I'm also running the original v1.0 BIOS on my msi p55 gd65 and this might be a good time to update. My question is what is the best order to do this in? 1. Retun to stock with a CMOS reset 2. Update BIOS 3. Replace chip 4. Overclock! Will my current windows installation be fine after all of this or will I need to back everything up and start again? Thanks! Dave.
