Current System
Asus M4A45 mobo
8 GB mem
160 GB Intel SSD (OS Drive, 500 GB additional Storage)
Phenom II 1100T X6 CPU
Asus Raedon 7700 gpu
OS: Windows 10

The games I play are
WOW
FF XI
FF XIV

Obviously, WOW and FF 11 aren't going to benefit much from an upgrade, but I was wondering whether the 6 core FX cpu would be any better than the phenom II. Or should I just wait until I can upgrade to a DX12 gpu
