There is a lot to like about Zotac's GeForce 8800 GT AMP! Edition – the heatsink has some subtle improvements that help to keep the temperature comparable with a standard-clocked GeForce 8800 GT at noise levels that are going to be inaudible in a chassis. It's also the fastest GeForce 8800 GT we have tested to date and, from looking around, there doesn't seem to be any 8800 GTs clocked faster than this – at best, there are equals out on the market. That maybe explains the overclocking problems we encountered.
