SLI med ett gtx 680 2gb och ett med 4gb ?

Can I mix and match graphics cards with different sizes of memory?

When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. However, while it is not recommended, NVIDIA does offer the flexibility to run graphics cards with different sized memory by using CoolBits. Using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode. When dissimilar memory sizes are enabled to work together using CoolBits, the effective memory size for each card becomes the smaller of the memory sizes.

Läser du ett par posts ner så länkas det till en lösning Nvidia har i sin FAQ (http://www.geforce.com/hardware/technology/sli/faq#c19) Dock vet vi inte datum på detta heller, inte hört Cooltbits nämnas på evigheter.

Det känns oavsett vad väldigt onödigt att köra på.
