We encountered some interesting results with the passively cooled MSI 7600 GT which decides to speed throttle when the GPU reaches higher temperatures (which are not even close to NVIDIA's 115°C alert temp).

Quote: "How high can you turn up the resolution and detail with these mid-range VGA cards? We evaluate their performance in six different games to give you the answer. Read on to find out how much *oomph* you can get for your money. The Powercolor X1800 GTO and MSI NX7600GT-T2D256EZ (the one with passive cooling) are tested."
