Sli 680 or one 690? - Page 3

These ones have the highest reviews in pcpartpicker: http://pcpartpicker.com/part/evga-video-card-04gp43687kr
They are $600 each though... But I mean, if 4gb to 8gb of vram makes such a big different, it sounds worth it. I would like to upgrade to 1440p someday if a monitor with 120hz and good input lag is released with it.
Edit: About the efficiency, does power requirement only affect my electricity bill or something else like making my pc hotter?

Vram is not a problem at 2GB until you get to extremely high resolutions with multiple monitors. The 2GB should be plenty.

As far as efficiency, the GTX 690 runs about 4C colder at load compared to the 680 SLI because it draws 50 - 100w less at load and has a different cooling system. So it will translate into it running slightly colder and not hitting the energy bill quite as hard.

***** you missed the deal i think last week Ncix had the EVGA GTX 690 for $869.99
post #23 of 31

i would go with two 680s in sli mainly because if one fails you could get by with just one. it also overclocks a bit more and  looks cooler i think.

How do the 4gb 680's scale into eyefinity? I'm curious because they actually have more vram than the 7970's, but everyone praises the 7970's.
post #25 of 31
the 680s don't handle memory bandwidth as well as 7970s, hence 7970s doing better at larger resolutions. The other thing to consider is that there are quite a few really nice 7970s under $400 now. That can not be said of the 680.

2 680's you will get better OC and performance on X79

if you had 1155 I would say 690 due to the pcie lanes

The 7970's scale better at extreme resolutions because of the higher bandwidth.

4GB is kind of overkill, bandwidth becomes more important and that's what the 7970's have more of.

Well, the main reason I'm going for NVIDIA is because 3D sounds interesting and deffinitely want 120hz, and the samsung 700d monitor is the only decent 120hz monitor for AMD and it has 11ms lag. The asus monitor seems like a more all rounded, and has 2ms input lag. Therefore I changed to nvidia complely so I could use the 3D and the Asus monitor.


I have a question, would bringing the video cards in luggage without taking them out of the box damage them? A friend is coming in a week and I could tell her to bring them as it would save me like $300 in tax.

And I may go for the 670's if the difference is only 5 fps, because that obviously isn't worth $300.

Yes, it's fine taking it in luggage.. not any different than shipping in a truck with a guy that throws the thing like a football. wink.gif

Haha ok great. I'm asking her to take the RAM, hard drive and ssd, OS and GPU's with her. I couldn't think of anything else that wouldn't bother her too much. Is the CPU big? I think it's small so I may also ask her to bring that.
