Hello, i was going to buy a XFX ATI 5970 black edition when i seen that the seller having put that the memory speed of the 5970 is 3.6 ghz instead of be 4.0 Ghz , i have asking him about it and he said that is 3.6 Ghz , so there actually a model of the 5970 with 3.6 Ghz of memory or the guy simple dont know what he is talking about and i can buy the video card without worrying about it

Thx in advance.
