Hey guys need some insight on this issue I seem to be having. I have 2 XFX Double D cards running in crossfire. Latest AMD 14.4 drivers, both on slots running PCI-E 16x. I get low usage when running games in particular BF4. Usage averages about 50-60% and about the same for the processor usage. In Spiderman 2 it's worse. FPS with v-sync on or off average about 40 depending on the environment. Am I missing something here? I had a FX-6100 and thought it was bottle-necking the cards so I got the FX-8350.

GA 990fxa-ud3 motherboard rev 1.1
FX-8350 OC @ 4.7~1.392v
H100i Corsair cooler
8GB Kingston Hyper X 1600mhz ram
2-XFX Radeon Double D 7870 1130 Core and 1400 Mem

Just an update. I've got the usage close to 90% with BF4 by using RP and turning off v-sysnc and using AFR for crossfire mode. FPS are also very pleasant. However, screen tearing pretty decent.
