5870 to 5970

[Spook187]

I am thinking of changing cards from my Asus 5870 to a Asus 5970

Although i am very pleased with my 5870 and handles the majority of my games flatout,but since playing the witcher 2 on high settings the 5870 struggles with uber sampling,getting another 5870 is not a option due to no crossfire board

you mention 5970 in the title and your post but the link is to the 6970, there's a big difference there.

My bad,yes its the 6970 i was looking at
