Well, I was wondering, because I have bought the EVGA GTX 670 FTW 2GB graphic card, if I was ever to SLI in future, could I just do it with the 4GB model that they offer? (The EVGA GTX 670 FTW 4GB), or would I have to use another 2GB card?

I would understand that the total memory, if I did SLI, would still be 2GB, yet having the 4GB card there also, for future may be helpful, when spreading gameplay across a 7680x1440 resolution. (For example, having a triple SLI on the 4GB cards, and using my 2GB card for the PhysX, if I've got that right...)

From what I've understood, there are some issues when mis-matching VRAM configurations. Sometimes, it just will not work, at least that was the case for the GeForce 500 series cards. I know that AMD Radeon HD have more flexibility when handling Crossfire.

Watch these:

These two videos cover everything there is to know about SLI/Crossfire. But to answer your question, no, I would not recommend you buy a 4GB card if you plan to SLI it with a 2GB card. Buy another GTX 670 2GB card.

Okay thanks for the advice, it sorta makes sence. Was unable to watch YT videos because of data useage cap of 3GB on my 3Dongle, but I get the idea of what you were saying :)
