Server is installing now.
Going to be running Tekkit, DynMap, etc...
Open to Tekkit-compatible mod suggestions, but we're gonna start with just those.
Server specs:
i7-990x Processor
16GB RAM (Going to try giving 12GB to MC)
500GB SATA 7200RPM for OS + DynMap cache (not perfect, but might upgrade in the future)
240GB SSD for MC + World Files (Hopefully killing our biggest bottleneck)
If this ends up having problems, I will migrate us to the new ESXi server which should be done this weekend as well... I just couldn't let this other machine rot as the only issue seems to be with the GTX580s which we won't be using.
I'll post again when it's done, should be 2-3 more hours.
