Gigabyte HD5870 Super Overclock
 

With the Dual inclined fans and all copper heatpipes the Gigabyte HD5870 Super Overclock is far from your normal HD5870 and it's one of the best designs we've seen for cooling and overclocking on Air. No whiny fan, no need to aftermarket cool, no worrying about voiding the warranty. Nothing but pure Graphics bliss pre-packaged on a HD5870 that has a 100MHz core OC with voltage headroom that should take it to 1GHz core if you dare?
