if you have an amd athlon x860k 4.3ghz processor, can you replace it with an intel i5 processor, does it fit? or do you gotta buy a better amd processor if you want to upgrade your processor?
AMD and Intel processors use a different CPU socket and mobo so they are not interchangeable. Your mobo maker should list on their website what model CPUs are supported by your specific model mob and what BIOS is required to use the newer/faster CPU. The BIOS would need to be installed before changing the CPU and you would need to "clear the CMOS" after you remove the original CPU and before installing the new CPU.
