I was going to use the SoftTH software to run three monitors on supported games like Team Fortress 2, Fallout 3, or Skyrim. SoftTH doesn't require cards to be in SLI, like surround does.
So one questioned answered. Thanks a bunch!
But the second question. Will my single GTX 570 be sufficient to run non demanding games like TF2, Fallout 3, or maybe even Skyrim with 25-30 fps?
