Other than those using Davinci, I'm not convinced that GPUs are all that heavily used in most better Video production tools. Many modern GPUs (other than the high-end CAD models) often sacrifice quality for speed so I think we'll see continued dependence on the CPU. I watched the recent Apple presentation on my 61" TV last night and was annoyed by the apparent lack of smoothing in the rendered iPhone games. Maybe it was a resolution conversion issue. I would think that stock analysis is more about data processing than raw number crunching. My financial advisor uses a thin terminal with a mostly text-based interface. She knows I'm not a fan of graphs and charts.
