For this article Nvidia supplied two GeForce GTX 770 cards and though you might have just read our reference article, I quickly wanted to show them to you with the help of some photos... hey, we know you love 'em.
The cards are 100% reference design as you can see. Above, 2-way SLI. BTW NVIDIA board partners will be allowed the create their own SKUs, so expect liquid cooled versions and different clocked AND cooled versions as well.
The GeForce GTX 770 will come with 2 GB of graphics memory, that's enough if you are a hardcore gamer with a monitor resolution of 1920x1200 and upwards. However, if you plan to game on triple monitors then 3+ GB starts to make a bit more sense as this will definitely help you out in the uber high resolutions and with hefty AA combinations. There a GTX 780 would make much more sense.
The GeForce GTX 770 has a maximum power consumption of 230 Watts (roughly 200W typical power draw), you'll need to power the card with two PCIe PEG leads from your power supply. We recommend a 550W power supply to start with (with one card of course) and then add 250W per additional card installed.
The GeForce GTX 770 PCB itself is based on a 6-phase power design with two added phases for the memory subsystem, thus that's a 6+2 phase design. The card is PCIe Gen 3.0 compatible. Going from PCIe Gen 2 to Gen 3 doubles the bandwidth available to the add-on cards installed, from 500MB/s per lane to 1GB/s per lane. Like any high-end GeForce graphics card, Nvidia will allow you to opt for the multi-GPU road as you may pair two or three cards in one PC -- heck even four if you are very rich of course.
