7870 crossfire for 5760x1080

post #1 of 13
Thread Starter 
My girlfriend got me 3x 23" Dell IPS monitors for my birthday as i am always talking about going eyefinity, I am currently using a 1090t but that may be upgraded to an ivybridge when it is released, but wanted to ask for your opinions on if you would go with a single 7970 card, or crossfire 7870's i know the 3GB Vram is nice, but would the crossfire setup make for a smoother fps ? Crossfire 7970's is too much so its either a single 7970 or crossfire 7870.

Thanks!

I'd say either 2 7870s or 2 7950s. At that res you'll need 2 cards if you want to be pulling a solid 60fps, and judging by BF3 you'd want 3GB of VRAM as well. 2 7950s seems like the best option if you can fit it into your budget.

If it has to be out of the two I'd say CF 7870s, but wait until the 23rd just to see what nVidia has to offer. It's less than a week away after all.

EDIT: http://www.hardwareheaven.com/reviews/1361/pg9/amd-radeon-hd-7970-graphics-card-review-total-war-shogun-2.html

That's a review that tests a 7970 at 5760*1080, you can see it isn't enough in a lot of games.

2gb of vram is enough since with 7870's he's not going to doing heavy AA/ultra settings anyway...

Neither will give you the framerates you need...what games will you be playing? Is there any chance you'll get another 7970 within the next 2-4 months?

My single 7970 at 1210core/1900memory plays BF:3 at the stock "Medium" settings smoothly, I dip down to 48 once or twice on caspian border which is the only time it's noticible on 60hz screens, since then I've swapped to 120hz single panel and haven't looked back as high resolution/FOV support is TERRIBLE in ALL games to the point where it's not worth it at all IN MY OPINION.

If you had the option to crossfire your 7950/70 within four months I'd say live with the lower FPS of a single card for now, and reap the benefits later. If this is a setup which you want to last three-five years (realistically only two for eyefinity 1080p) then get the 7870's.

Have fun!

you definately wont get what you want with a 7970. 5760 is just too much for a single gpu card on most games. the 7870s are indeed powerful for the price but they still are not as powerful as a 580 in most cases. i game at 5760x1080 on and off with my sli 580s and believe me you arnt going to want less than that if you plan on using more than 2x AA or 8x AF. actually right now the 7970 or 7950 in xfire may be the only single gpu cards that (when xfired) can handle 5760 x 1080 comfortably.

IMO wait it out. wait until ivy. thats what im currently doing. by the time ivy gets here a 580 will likely be in the $300 range, making them cheaper than a 7870 currently and still more powerful. and with the release of the GTX 680 you will likely see the 7950s reach the $380-400 area(current area for a 7870 Twin Frozr).

what gpus are you currently using?

I tried BF3 with 2 x HD 6970 @ 5760x1080 and anything over Medium was laggy.

This is very true. I bought my triple screen setup for iRacing, which it works perfectly on. No stretching, correct FOV settings. Its awesome. Every other game I've tried is absolutely awful. BF3 is one of the worst. Big time stretching and distortion on the sides. FOV is all screwed up and large FOV's aren't supported at all. You hardly even see any more than one monitor because of all the stretching.

Go with a single 7970 for simplicity with Eyefinity. If you need more then add another 7950 or 7970.

 

This is a single card performance Sapphire HD7970. It doesn't have to be Sapphire, choose one with known good support and warranty.

Hmm. I'm in the same boat, but mine is rocking 3 ways.
2x 7870 now and have everything finished.
1 7970 now and another when I get the available money.
1 GTX680 now and another when I get the available money. (When this is released)

So far I feel like waiting to see what Nvidia has to offer. They seem to be pretty confident of their "mid range" card.
I suggest the same. Like the other guy said, it's only a week from now. thumb.gif
