Matched with which graphics card(s)? I can't speculate; there are too many variables. Far Cry 4 is a new title which I've never run.
I still have a Q9650 overclocked to 4.2 on an Asus P5Q Deluxe with 8GB DDR2 1066, an SSD and an overclocked GTX 760 in a modified Cooler Master Elite 330. For a six year old socket 775 platform, it's still a nice rig, and I'm still impressed with the speed. It's always been one of my favorite builds.
