Xfx 6770 vs sapphire 6770 vs asus 6770

XFX generally has better warranty terms (double lifetime warranty, if you ever decide to sell the card), but they and Asus are somewhat known for being slow if you need to RMA. However, Sapphire and Asus are known for making very reliable products, and Sapphire is one of the best AMD GPU manufacturers (since they only make AMD GPUs, like EVGA and NVidia).

All in all, unless there are some glaring and widespread issues with a specific model/series of the GPUs you're looking at, any of them will be fine.

But doesn't the XFX use a 256 wide bus while the Sapphire only uses a 128 wide one?
 


I'm not sure - you just posted 3 manufacturers and the same model of GPU. I can't be more specific unless you give specific examples.

If I were you, I would go with xfx, because of their warranties and customer support. They are the most known and popular brand for that reason, plus their cards look sweet. Performance wise won't be much of a difference, considering it's the same GPU.
