Right now you can find 3 different Gigabyte GTX 780 Windforce OC models on the market:Gigabyte GeForce GTX 780 WindForce 3X OC Rev. 1.0 (GV-N780OC-3GD)
Rev. 1.0 was the first model using reference PCB layout, WindForce cooler and some gpu overclock. All cards are using GK110-300-A1 chips with 80.10... bios. Not sure if they are still in production or retailers are just selling off their stock.Gigabyte GeForce GTX 780 WindForce 3X OC Rev. 2.0 (GV-N780OC-3GD)
Rev. 2.0 was the second model using custom PCB layout (8+2 phase), 2x8-pin PCIe connectors, WindForce cooler and the same gpu overclock as Rev. 1.0. Since B1 is avaliable, Gigabyte is mixing GK110-300-A1 and GK110-300-B1 chips in production until switch to B1 is completely done and A1 stock is emptied. So right now you can get lucky with a B1 chip.Gigabyte GeForce GTX 780 GHz Edition WindForce 3X (GV-N780GHZ-3GD)
GHz Edition is the newest addition using custom PCB layout (8+2 phase), 2x8-pin PCIe connectors, better memory chips, full cover backplate, WindForce cooler and further increased gpu overclock. (see here
). With this card Gigabyte guarantees 100% GK110-300-B1 on a slightly improved card for a little price premium.
Checking my favorite shop, GHz Edition is €470 versus €440 for the Rev. 2.0 right now (both in stock). The GHz Edition is the one i currently plan to replace my trusty GTX 570 with, because the price premium is low and the mixture of high stock clocks / good custom PCB / quiet WindForce cooler sounds very sexy to me. But since B1 chips are fresh and - after release of R290(X) and 780Ti - gpu prices are changing almost daily, i try to keep my trigger finger from the "order now" button for some more weeks. Maybe after christmas ... depending on custom 780Ti prices ... who knows ...
