Diamond Radeon HD 3870 1GB Graphics Card Review
 

"In a couple of cases, mainly in Bioshock and World in Conflict, the extra frame buffer made a noticeable impact on our gaming experience and allowed us to play much more comfortably at the 1920x1200 settings than on any other single-GPU AMD graphics card. In the rest of the titles we played through the 1GB card offered no benefits over the 512MB versions - and this was surprising in cases like Call of Juarez that are heavily dependent on memory subsystem performance."
