Sapphire HD 4850 Toxic Review
 

Instead of the fancy VaporX cooling solution we saw on the Toxic 4870, you'll receive a ball bearing cooler from Zalman. It uses only 512MB of GDDR3 memory clocked at 2200MHz and has a slightly overclocked core (675MHz). The Toxic 4850 is nothing more than a normal 4850, but for many consumers, that is more then enough power.
