Originally released to compete with Nvidia’s GTX260, the 4870 was a massive success for AMD and its partners and helped them to re-establish them as a dominant force in the high end marketplace.
Sapphire are the biggest AMD graphics card partner and a few months ago they released an overclocked version of the 4870 (Toxic edition) carrying a custom cooling solution. However, that version only shipped with 512MB of GDDR5 memory which wasn’t ideal for the growing demands of high end enthusiast users.
Today we’re looking at a new offering from Sapphire based on the original 4870 Toxic. This edition now brings 1GB of memory to the table to combine with the pre-overclocked frequencies.
