Do you plan on just 1080p gaming? Even if you SLI in the future, you may not have enough VRAM for that much longer on any higher res screens since VRAM doesn't stack when adding more cards. Another thought, though. I saw you chose an NZXT case. I don't know if you've ever heard of the NZXT H440 case? I think it's a pretty cool case and recommend checking it out if you haven't.
