These are two Gigabyte HD5870 1GB videocards. They were bought at Newegg.ca at the beginning of summer 2011 and have been running in Crossfire. There is still 3 year warranty through Gigabyte.
Due to a change in the numbering scheme for ATI products for marketing purposes, the 5870's successor is not the 6870 but actually the 6970 and therefore, the 5870 slots between the 6950 and 6970 in terms of performance. The 6950 has 1408 stream processors or shaders. The 6970 has 1536 shaders. The 5870 has 1600 shaders. Aside from raw clockspeed, the shader count is the main factor in card cost and performance. 1GB of vram is more than sufficient unless you are running very high resolutions and antialiasing (ie: 5760x1080 with 8x AA). The main improvements of the 69xx series are improvements in tessellation performance in dx11 which nets the 6970 about a 5-10% faster performance over the 5870.
