Solved 7970 going Crossfire, good enough system? Tags: Graphics Cards Battlefield Crossfire Graphics Last response: September 22, 2012 11:32 AM in Graphics & Displays Share Charybdis September 22, 2012 6:19:09 AM Hi I am planning on getting another Sapphire 7970 OC for a Crossfire setup. What I have (That I think is relevant): i7 920 D0 (At stock speeds still) Asus P6t SE A decent 750W Corsair PSU 1920x1080 x3 Eyefinity My 7970 takes up more than 2 slots on my motherboard, which means I have to use a x16 x4 slot on it. This (From TechPowerup) shows that PCIe 2 x4 should be enough: (I mainly play BF3) My other concern is the PSU. From what I have read, I think it should be enough. At the moment, when I play BF3 on Low @ Eyefinity resolution, my CPU usage hardly ever goes above 45%, which is why I haven't overclocked it, also why I think it would not be a bottleneck. Can someone please clarify these? I would hate to find issues with a $469 card Thank you More about : 7970 crossfire good system Best solution bigcyco1 a c 178 U Graphics card September 22, 2012 6:39:01 AM Much better to upgrade to an 850W+ unit in order to both have overclocking flexibility and headroom on the 7970s Charybdis September 22, 2012 10:50:00 AM I get that it might be on the limit, but I am trying to get away with this PSU. Tight budget. Would it be able to run stably? Even without overclocking?
