Puzzling performance of RX 480 vs my old GTX 660

I just bought a rx 480 to replace my aging gtx 660. I am getting good fps on my recent games(Doom, ROTR, Fallout 4, BF1 etc) and the OC seems stable. I fired up crysis 1 just to enjoy the performance differential between the 480 and my old gt 9600 (with this gpu I played crysis back in the day). The fps with 480 seemed way too low and the gpu/cpu utilization was very low too. I reinstalled the 660 and got better fps. Plus with the 660 both the CPU and GPU seems to be hitting 100% utilization. I am seeing the same thing with borderlands 2, getting less than 60 fps sometimes - mostly at 90fps. I have cleaned both nvidia and amd drivers with DDU, installed 17.2.1, 17.3.1 and 17.3.2 drivers after DDU cleaning each. Now I am just sitting here scratching my head. The processor is a i5-4590 btw.

My OC is this one. Temp limit set at 90 degrees. The card goes up to 79 degrees after 12 minutes of 3dmark extreme, the ambient is 33 degrees btw. I don't think power delivery could be causing this - Doom runs at 150-180fps at ultra and Rise of the tomb raider at 68fps with mostly high settings.
