This is a gaming cpu Hierarchy chart that Tomshardware puts out once a month and it lists the cpus by order of best to last. I know that your doing a home server but this just gives you an indication of where Intel cps are when compared to AMD cpus. You'll notice that there are no AMD cpus in the top two levels.
If your just building a home server that doesn't need a high powered cpu then you can go for something less than a FX-6200 or i3-2120 and look at the G-870 and G-860 , they are good enough for what you need and inexpensive as well.
That doesn't apply at all to OP. Servers are extremely good at using all threads and games are generally not at all. The 6200 would be almost twice as fast as an i3-2120 and an FX-8150 would trade blows with the quad core i7s, both of which would beat the i5s by a good 20-40%. Any Pentium would be far more than necessary for a home server anyway. Again, an Athlon II x3 or a Celeron G530 are the best options for OP.
