I feel like I am already pushing my PSU to the limit, but I figure I would ask for a second opinion. I am considering getting another graphics card to use in CrossFire, but I'm not sure If my PSU can handle it. Here's everything my system:
Antec 750W power supply
ASUS M5A99FX Motherboard
AMD 9370FX CPU
CORSAIR H100i liquid cooler
SAPPHIRE 100314-2SR Radeon 6870 graphics card
CORSAIR 8GB (2 x 4GB) RAM
Two WD 1TB Black WD1003FZEX hard drives
Four WD 1TB Blue WD10EZEX hard drives
Intel X25-M 120GB SSD
DVD ROM
Two front panel Card readers

Anyone willing to look at my components and think if I can get away with another Sapphire Radeon 6870 graphics card in my computer? I would greatly appreciate an opinion or two.

Thanks!
