I currently have a Sapphire Radeon 5850 1gb card, I want to buy another 5850 in the next months, since the only available cards here are powercolor(abundantly), should I just get it or place an order fo the exact same 5850 I have. I am still scouting for the ud3a which isnt readily available here either...
Also If I do get hands on a 2gb Toxic, would my total memory in crossfire only be 2 in crossfire or 3?
Indeed, if you add a 2gb 5850 it`s speed will be reduced to 1gb to match the other 5850. Buying a 2gb 5850 will be a waste of money. It`s better to have cards with the same memory
Having 2x1gb cards wont increase your VRAM to 2gb as your system won`t recognize them that way but it will reconise it as 2 x 1gb GPU`s.
Even a single Radeon 4870x2 is reconised as having 2gb of VRAM on CCC
