Hello, everybody.
I am building a gaming computer and I am having trouble deciding which graphics card I should get. Should I get a GTX 780 or run a pair of 680's in SLI?

Here are my confirmed system specs:
Intel 4770K
Asus Sabertooth Z87
16GB of Gskill Trident RAM
1000 watt psu
Thermaltake Chaser MK-1

I will be playing games along the lines of Minecraft, Team Fortress 2, Battlefield 3 or 4, Planetside 2, and Portal 2. Do you guys think these games will run better IN NVIDIA SURROUND with a single Gtx 780 or two Gtx 680's?

Thanks so much!

A single card is always better then two running in SLI. But in terms of performace, i would personally get sli 680's. However, SLI can have problems. You will often run into driver issues, have micro-stuttering and increased heat and power consumption.

Do you already have 1 680? It doesn't make sense to buy a 680 right now, with the 770 being about the same cost.

680 SLI will have more FPS, the 780 will be able 20-30% faster than a single 680, but 680 SLI should be about 40% faster than a 780, but frame delivery won't be as consistent as a 780, even though it is generally good, but it is not perfect.

+1 it is always better to go with the best card you can afford and go SLI later. With an agressive overclock, the 780 can be quite a bit faster than the 680. Either way, as stated, if you do decide for immediate SLI, get a pair of 770's. Same cost for about 20% more graphics.

Thanks for your answers guys! Because of your answers, I have decided to go with a single gtx 780, but if I were to go SLI with 2 780's later, do you think a 1000 watt psu will be enough? The rest of my system is stated in my original question. Thanks so much!

Yes, http://www.tweaktown.com/reviews/5507/evga-geforce-gtx-780-3gb-superclocked-video-cards-in-sli/index22.html you'll see that it only brings 755 on load with a 3960x at 4.7ghz. Just make sure you have enought connections for them

Yikes! Not so fast. It seems the ASUS Sabertooth is not a real good motherboard. Dust collects under the huge shroud and the board can overheat.

I'd recommend this baby:

If you can swing it, here's a nice new power supply, top quality, from, of all people, Cooler Master:

It is fully modular with flat cables so they route easily and stay down. it is more efficient than Platinum models when idling.
