GPU decision time.

If you'd use a single GPU, or wouldn't mind crossfire, then I'd recommend waiting until the R9 380X was out, as some leaked benchmarks are actually listing it as beating the Titan X. If you're desperate for SLI, though, this might not help much. It's still possible that if the 380X genuinely does beat the Titan X at a lower cost, it could encourage a price drop, which you'd benefit from.
