sli 680s or sli 770s?
So for this discussion the 680s and 770s in question will be evgas 4gb ftw version of both. I will be upgrading soon and wondering what peoples thoughts would be on which is better but mostly which would last longer. I currently have a evga 660 SC 2gb but will be upgrading to 3 screens running at 5760x1080. I will use the 660 as a physX dedicated card. I am expecting to be able to get the 680s for $490 and the 770s for $480. Games i will be playing include Arkham Origins, BF4, AC4, and Watch Dogs. Thanks for any help!
Same GPU but the GTX 770 has some newer features, it's generally cheaper, and faster. The only reason you would want to get a GTX 680 is if you already have a 680 and want sli. Also you don't need a 660 for physx. You would be better served selling the GTX 660 or putting it in another computer.
You would be fine getting two of these http://www.amazon.com/EVGA-Superclocked-Dual-Link-Graphics-04G-P4-3774-KR/dp/B00E5AEIKE/ref=sr_1_2?s=electronics&ie=UTF8&qid=1382386846&sr=1-2&keywords=GTX+770+4GB
It's already going to be powerful enough as is.. The slight overclock on the FTW edition cards won't make a huge difference and even then you could safely overclock to those speeds anyway on the SC edition.
