i'm running an FX-6300, and just seeing the difference between the Zambezi and Vishera chips, i'd say it won't be too long before that becomes your bottleneck (assuming a decent GPU) with how much slower the bulldozer cores are and being at only 4 of them. Then again, my CPU will probably start to bottleneck with how some of those games look... I'd suggest looking up a review for your processor, there's tons of them, and look at their gaming benchmarks for current games, with some extrapolation you'll probably be able to figure about where you'll be sitting in the future.
