This is Ivy Bridge, not Sandy, but frankly apart from Intel cheeping out on the TIM by using paste instead of soldering it may as well be the same.. arguably worse since Sandy could generally be overclocked further.
That 3770k system got turned into a Proxmox server; pfsense, TrueNAS Core, few other misc low demand VMs.
Here's the rub: I recently swapped the 3770k for a 3770 because the k model does not support VT-d for some reason.. I had to use PCI-E passthrough in order to use TrueNAS reliably (NICs and an LSi HBA for the six SATA drives).
Really the biggest limitation for me is core count and ram, I'm maxed at 32 gigs and ZFS loves ram. There's other quibbles like Asus not issuing an updated bios to implement Microcode updates on my P8Z77-V, but the Linux kernel has mostly mitigated it in software to the point that the remaining vulnerabilities are the kind I'm not concerned with.
I'm hoping to build a replacement next year.
I would like to talk about how great my 3770k was for lasting so long but really it's just because for gaming there was little incentive for a long time.
