The point of a high end GC or a pair in SLI/XFire is that you have a need for it. It could be a large monitor, multi-monitor setup or something like folding. If you don't need that power, then no real need for a top-tier card. EDIT : Unless you want a high-end, top-tier setup just because you can. Here at TPU, the word "overkill" doesn't really have much meening.
