hello, just curious which would be the best choice:
a MSI gtx 560 ti, pny gtx 560 ti, alienware i think gtx 560 ti 1.25 gb vram or a xfx hd 6950 [says its unlocked to 6970] or refurbed vision tech 6970?
all are used and the only refurbed one is the 6970. also, if i can, which would be the two best to CF? the guy is selling 2 6950s but i think you can CF 6950 and a 6970 (correct me if im wrong)
and is there anything wrong with buying a used gfx if it has a 15 day money back warrenty?
and is there anything terribly wrong with buying used?
Nothing terribly wrong. If you are getting it at a great price & buying from a seller with good reputation, you should be covered specially if the item has double lifetime warranty or similar coverage.
