  1. Hi

    I'm currently using one gtx 570 from Palit, and wanted to buy second one to use it with three monitors. I wanted to ask if this setup will allow me play BF3 on multi monitors on ultra high details? And what PC power supply I should buy to run it stable?

    Here is my spec

    CPU: i7 2700k @ 3.5GHz
    Mainboard: Asus P8Z68-V LX
    RAM: 8192
    GPU: Palit GTX 570 1.3GB

    1.25GB of VRAM is not going to be enough over 3 monitors, especially with a demanding game like BF3. Remember when you add another card in SLI you don't get double the VRAM, the useable VRAM will still be 1.25GB.

    If you want to go triple monitor you should sell your 570 and get a 670 2GB or 7950 3GB at the very least. If you want to play at full ultra details on BF3 (I.e. 4x MSAA) you'll need SLI 680 4GB or CF 7970. You're tripling the number of pixels you need to push, it won't come cheap!

    A good 700-750W PSU will be enough to run a SLI/CF system. But only from a reputable brand, not some cheap PSU which claims to output 700W.

    These sli 680 are required for one or multiple monitors for ultra high details?

    One 680 is fine for a single 1080p monitor. Over 3 monitors you'd need an SLI setup because you're pushing 3x the number of pixels. Even with 680 SLI I don't think you'd be able to run at full ultra at 5760x1080, you might have to turn down to 2x MSAA.
