If it's for gaming, you don't change that CPU. It's more than enough for say 3 video cards. Noted at:
"Our tests demonstrate fairly little difference between a $225 LGA 1155 Core i5-2500K and a $1000 LGA 2011 Core i7-3960X, even when three-way graphics card configurations are involved. It turns out that memory bandwidth and PCIe throughput don't hold back the performance of existing Sandy Bridge-based machines. "
The CPU is comparable according to http://cpuboss.com/cpus/Intel-Core-i5-2500K-vs-AMD-FX-8150
I'm very interested in the new AMD Zen Core cpu that is slated to come out sometime in 2016. Unfortunately for my wallet, this will mean a new AM4 socket mobo which will also mean new DDR4 RAM. Choosing the compatible products when the time comes will not be an issue, but once they are swapped in... then what? I imagine my computer will recognize the new CPU upon boot and prompt me to enter the setup/BIOS. But isn't the BIOS on the mobo which is also new? Maybe I'm over thinking things and the computer will work out the new hardware on it's own, but it just seems like I'm going to run into a conflict somewhere and it won't be as easy as out with the old and in with the new. Here are the specs of my current set up:
ASUS Crosshair V Formula mobo
AMD FX-8150 cpu
Mushkin Redline DDR3 RAM (8gb @ 2133mhz o.c.)
Tt bigwater 760+ which won't be compatible with AM4
Any insight on what this swap is going to entail, outside of the physical swapping of parts, is greatly appreciated!
