Hi

Specs:
EVGA GTX 780ti ACX cooler (1250Mhz) GPU
Intel core i7 - 4770k (4.1 Ghz) CPU
ASrock z87 Extreme6 MOTHERBAORD
Corsair CX750 modular PSU
DDR3 4 x 4GB (16 GB) DDR3 1600Mhz RAM
2TB HDD
64GB SSD
Thermaltake A31 CASE
Corsair H100i CPU COOLER
5 x Corsair SP120 Quiet Edition CASE FANS

all games run at ultra at 60+ fps at 1080p
but dont at 5760x1080
I play games like CODs, BF3/4, GTA, assassins creed, just cause 2, tomb raider, far cry 3, watch dogs etc

ive looked and the majority of my games max out the 780ti at 99%

If i get another 780ti SLI, does the usage on them both go to 99%?
And im using EVGA acx cooler, will it be okay in terms of heat to have 2 780tis next to each other?
My current one on max load gets to 70c avg and 74c max
and can a 4770k handle 2 780tis?

Thanks

780 Ti should run everything fine on Medium-High with 5760x1080 resolution. Go find a 780 Ti review and go to the multiple display section.

Yes i know that, but i want to run my games at ULTRA with max anti aliasing at solid 60fps at 5760x1080 (bezel correction too)

so the 780ti isnt doing this on the latest games aka watch dogs
since i really dont care how much i spend on my pc i decided another 780ti would be wise
except ive never even seen a SLI system running before and would like to know how well it all works
(would like to be educated in this area)

Thanks
