I think in the long run it is worth an extra $32. Most people will say that the GT is the best value, which I also agree with, but considering that an aftermarket cooler will cost about $30-40 more I feel that its well worth it.
I first went with a BFG 8800GT and it was to loud and got a bit warm. Now I'm running an EVGA 8800GTS and couldn't be happier.
I'll second this. If you want a little more hassle free and the slight boost in performance go grab the GTS. Personally I got my BFG 8800GT OC at BB for $237 back in November. I then spent about $30 in cooling for it so I could OC it. The GTS has the nice dual slot blow the hot air out the back design.
