nV News has posted a Tweakmonster Copper RAMsinks review

Who would have thought back in the days of the Riva 128 or the good old TNT that memory would eventually become a limiting factor in 3D graphics performance? Back then we concentrated on overclocking the graphics processor and didn't pay that much attention to memory. Advances in memory technology which include the dual data rate (DDR) memory first used on the GeForce 256, we found that additional levels of performance could be realized by increasing the memory speed beyond its rated frequency. With faster DDR memory appearing on the the GeForce2 and GeForce2 Ultra, factory installed memory heatsinks became a common feature which has continued with the majority of GeForce3 based graphics cards. While they are effective in dispersing heat, they are often necessary in order to avoid overheating problems.
