Having already taken a crowbar to prices like a spree-killing Yellow Man, the 4870's refresh seems overdue. The card, stonkin' as it is, has an annoying stock heatsink and a lot of untapped overclocking potential. There's a short list of non-stock, factory-overclocked 4870s that need reviewing. First on my list is Palit's Radeon HD 4870 Sonic Dual. With its long heatsink and large fans, not to mention namesake, the thing promises quiet, and at the flick of a switch, overclocking. Not everything stood up to scrutiny. At least it's still inexpensive.
