Hi Guys, I have recently brought 3 BenQ GW2750 LED screens and im running them off 2 XFX HD7850 cards (2x DVi-D, 1x Mini Display Port) I am struggling to play games at full or close to full graphics, is it that my cards aren't powerful enough or do I just need to turn the settings down?

Computer Specs,
CPU: i5-3570K @ 4.0GHz
RAM: 16Gb Corsair Vengence Black
Motherboard: Gigabyte Z77H-UD3H
GPU: 2x XFX HD7850 Black Edition
PSU: CoolerMaster M2 1000w

Thanks
Paul..
 
Hi Paul,

What type of games do you play?

I'm assuming its down to pure graphics power

Any ideas anybody else?

It's probably the fact you're driving an effective 5760x1080 screen. With my 6950 CF I couldnt run many modern games at full graphic settings and get a high frame rate. If you're using antialiasing, drop it to x2 or none, it'll be the biggest frame killer.
 
7850 CF is roughly the same as a single 7970.

I can say from experience that you need tot urn plenty of settings down to run games at playable frames using eyefinity on a single 7970/780CF.
 
If it's any help I could play a lot of games on high with no aa on CF5850s, on CF7970s I can run most with high and aa, some frame drops but nothing too major!
 
"Brought" :(

It depends entirely on the games but 2 7870s should be fine for quite a few games at 5760x1080.

I played quite a few games at that res on a 6950 and 5870 with decent performance.
 
Thanks for the replies.. and sorry about the terrible grammer :(
I think the problem is that I'm trying to push the cards too hard? When I was running a single card on a single LCD screen I had everything at maximum including the aa turned up as high as it would go and it ran them fine. But then I was only running at 1360x768 res. Like previously stated, I'm effectively trying to run a 5844x1080 res screen at the same intensity.
From what you guys have said though, sounds like I should have got better cards from the start.
Time to get saving for the Christmas sales?

I ran eyefinity for a while with a single 7970 and it performed better than my old 6970 xfire, im not 100% but i think for some reason crossfire and eyefinity does not play nice together
 
eyefinity requires some raw horsepower, and run max is a 7950crossfire or such hardware.
even then due to game and such it might not run flawlessly.

I choose a single 7970 and oc to 1200mhz and turn settings down until it match what I want when gaming.
 
With SLI 680's, I am starting to see newer games struggle at max detail. Far cry 3 for instance runs very badly at 5760*1080. Hitman Absolution isn't too bad but still seeing ~45 fps average. If you are struggling with newer games, I would feel it is just a case of GPU grunt being the failure.

Get swapping big man :p

Only kidding of course.

Yeah that also another reason why I downsized. If I didn't keep on the upgrade curve by selling and going next generation I'd be left having to shell out again just to play games at decent settings.

As I won't have much time to game in the next 6-12 months it was time :(. Do miss it though when I do get on the PC.
 
I bet you miss it bro. When I sold my EVGA ref card, I was down to one screen and just for browsing, I found it annoying. I generally have a couple of tabs open and one of those tabs will be dragged across to another screen (ideal for 3DMark score updating). Gaming was the worst though, one screen gaming would be acceptable but hard to enjoy again.
 
I was wondering if maybe trying to plug the screens over the two cards would work? as at the minute they're all plugged into one of them?
A bit noob-ish question I know, but never dealt with multiple screens/GPU's before?
