Sapphire, FIC, and Gigabyte all overclocks pretty good. HIS released 1 with Ice-Q cooling and it's really good, and Geil released new 1 using Thermaltake's Giant2 heatpipe cooler with 2.2ns Hynix memory, and the card's default frequency is at 450mhz/740mhz so it's a 70mhz increase in core by default from ATI's refrence card.
