I am looking to be able to raid in high settings with at least 60 fps during boss fight.
Would this be enough or would I need some upgrades?
No rig would guarentee you a solid 60fps on wow. Its more down to the networking and server sync. On 25 man fights your going to take a big fps hit no matter what.
WoW its self doesnt require high end hardware. The spec you quoted is way over whats needed to max the game out.
Exactly, while it is nice to not bottleneck yourself with hardware; your real concern is your isp bandwidth. Make sure you are rocking top notch interwebs and you will see the least amount of problems.
