Re: SLI GTX 560 on Crossfire Mobo
1: You will be limited to the card with the lowest amount of VRAM. SLI and Crossfire mirror their buffer and so you're limited to the card with the lowest amount.
2: I've used it before in its infancy state (2009/2010) and it worked and did last year with HyperSLI. Bout all I can say, as I did it on a 790FX board, and P55 board. Is it reliable? Not really, see below.
3: No. Most driver updates break the SLI hack and so you need to wait for a HyperSLI update before updating drivers.
It should work decent on your motherboard, as you can do dual 8x mode whereas my Crossfire only boards were 16/4. That hampered things a lot. In my totally honest opinion, it's not worth the hassle.
