7680x1600, Should I go with 4GB 680s or 7970s?

post #1 of 41
Thread Starter 
Hey guys, I am hoping for some unbiased opinions on whether I should get 2x 680 4GBs or 2x 7970s 3GBs. I'd really like to hear from other people running similar resolutions. I have been an Nvidia guy for years now and prefer their drivers and the NVCP, but I have heard that maybe the 680s don't perform as well at ultra high resolutions such as 7680x1600 or 7680x1440 because of bandwidth limitations so I might be willing to go with AMD. Finding benchmarks for this resolution has been impossible so I was hoping to hear from some of you guys that are running these cards with 3 high res monitors. And BTW I realize I should probably be looking at getting 3x of whatever card I decide on, but I only have money for 2 of them now and will be adding a third down the line. Thanks so much for any input.

If you wanna make sure you have more then enough RAM there is the sapphire VAPOR-X HD 7970 GHz Edition with 6GB of RAM sould be able to run just about any resolutions but i think that a 4 GB GTX 680 could do the same just fine

In that configuration, I suggest using AMD cards. AMD's drivers have actually been improving greatly. Also, if you look at the benchmarks here: http://www.legitreviews.com/article/1887/4/, the HD 7970 falls slightly behind in single-monitor performance, but edges forward in multi-monitor performance.

Also, with a 3x card configuration, the X79 platform would be a good choice.

I have seen this go back and forth, and up until 1600p or lower the 384 bit bus doesn't do a damn thing. However, at eyefinity/3DS resolutions it will present a slight advantage.

It it were me, I would go Tri-SLi 4GB GTX 670's or 680's.
You get FXAA, outstanding PhsyX performance and the overall superior driver package IMO that comes with buying a GTX.

If you want the best GPU on the market, Keplar is the answer.
Want to save some money and still get awesome performance with an OC? Southern Islands isn't a bad choice.

You can't go wrong with either but I would go with a GTX setup, the bigger bus doesn't make up for all the Radeon's shortcomings. Not trying to start a war just my opinion based off experience with both companies.

For multi monitor HD 7970 is slightly ahead. But because of your comfort level in the past with Nvidia products just get the GTX 680 4GB. thumb.gif

Thanks for the opinions guys. +REPs to all. Does anyone know of any review sites with benchmarks at multi-monitor resolutions? I'd really like to see some head to head numbers even if they are as low as 5670x1080. Obviously the higher res the better, but I don't think benchmarks as high as 7680x1600 exist on the internet right now. It's just that everywhere I look some poeple say Nvidia and others say AMD for multi-monitor with no hard numbers to back it up. Does anyone here run these cards at this res themselves and have some numbers? thanks again guys

In my previous post, I had a link to a benchmark comparing a GTX 680 with an HD 7970 in 5760x1080 performance. In BF3 with the Ultra preset, the GTX 680 got 29.5 FPS, while the HD 7970 edged out slightly at 30.9 FPS. 

Also, check out this benchmark:

I would go with the 7970 because it has a larger memory bus. But the 680 isn't bad.
