i'm getting god awful fps in every one of my games. i recently upgraded to a 7990 thinking it would help my problem, but nothing changed. exact same fps. which tells me it's my processor? idk. i had an FX-6200 @ 4.1, 16gb ram @ 1866, an AsRock Extreme3 990fx am3+ mobo. i previously used 2 660ti's in sli, and at first, i had wonderful frames. but 1 day, (with no updates, no drivers, no restart, no nothing) my fps just tanked. i struggle for 60 in every game, when i was getting over 100 maxed in every game. battlefield 3 for example, i used to get 90-150fps on ultra w/ 2xAA, motion blur off. now i struggle for 60, same settings, even no AA i struggle for 60. i thought it might have been 1 of my 2 cards, but i tried them both individually, but they both worked fine. i wasn't getting that much worse fps either. with my new 7990, i get the exact same fps, crossfire enabled, or not. (vsync is my enemy, so it's never enabled). is there something i'm missing?
please help! i want my frames back! i did not spend this much money for a struggling 60!
yeah, i'm pretty sure my cpu is bottlenecking, but i'm already using the 13.8 beta, and i used to have really awesome frames even with this processor. now i can't even get close. this thing should be able to take me above 60, and with the 7990, i'm barely getting up to 60 in battlefield. i'm gonna try a reinstall.
Have you checked to be sure these cards were getting enough power? I had this issue on my old GeForce 5600 Ultra when the PSU started to fail. Maybe try hooking your PSU up to a tester? They're about $6 on Amazon. I don't think that the CPU is that big of a bottleneck and it doesn't seem likely considering he was getting 90-150 fps on the same CPU before. Hope this helps.
Personally think the rig is still decent for gaming. 99% of DX 11 games still only use Quad Core. Even my buddies QX8600 4.5 GHZ flies with FPS playing today's games.
IMO keep the 660 SLI upgrade to a SSD reinstall inculding most recent GPU drivers. In less you're overclocked the refresh rate 60FPS is fine. If you want some crazy FPS then socket 2011 with x79 is going probably be your best bet If your 7990 is still bottlenecked.
yeah, i got the 7990 cause it was cheap as hell and i planned on getting new stuff later on to go with it. ill check the idea of not getting enough power. and i was wrong, i had 13.10 not 8. i might just get a new psu alltogether. this one's aged a bit. it's an 850w 80+ but it's got a few years on it.
i've thought of the whole 'game doesn't like crossfire' thing, but battlefield is very crossfire happy, and scales like 90% or some other outrageous number. and even then, the games i play, a single 7970 should get me plenty of frames, but it's not. (p.s. i turn xfire on and off to test my games to see what works.)
