8800gt vs 3870

I've been looking at upgrading my graphics card (just got the GT5636E Quad)... I've been really interested in the 8800gt, but seems like every site I check has people have noted problems w/ either the fan speed setting being to slow, heat issues, noise problems, or a mixture thereof. According to the benchmarks, the 8800gt is supposed to be better than the 3870, but I'm starting to wonder if the 3870 wouldn't be a better route... anyone know of a good 8800gt brand to go with? I've read the reviews of the XFX & EvGA, but they have the same issues as the rest of them. Any help here would be much appreciated...
