I currently have an A4 5300 CPU, and am planning to upgrade to Athlon X4 860k.

Here is my current setup:

AMD A4-5300
Deepcool Gammaxx 200
Gigabyte GA-F2A68HM-S1
Sapphire R7 250X 1GB DDR5
Kingston HyperX Fury 8GB DDR3 1866MHz
Seagate 250GB + 500GB HDD
FSP Hexa+ 550
Windows 7 Ultimate
Cooler Master K280


Question is, do I have to reinstall Windows 7 after upgrading my CPU?
