its not recommended to mix two cards with different memory. you may have to adjust it manually, as per what NVidia has on their website:

"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."

No. If you SLI a 2gb and a 4gb card it will act as if both cards were 2gb cards, at least with modern cards like your 760.

On a side note.. The main text of a forum post should be in the thread and not the title.
