I currently have a galaxy GTX 470, never had an issue one, it's quiet, overclockable, and still provides me with a pretty good gaming experience. It's one that you can adjust the fan direction, and I really like having that capability, even if I don't use it...but I may need it. Plus, the card was a lot less expensive than similar models when I bought it for the same performance. Great products...and much more versatile than my old BFG stuff when I was using them.
This Galaxy card isn't special. It isn't exceptional, nor is there anything to criticize as far as I can tell. It's just like any other GTX 670 (aesthetics aside). But, the generous warranty is what differentiates the Galaxy brand from others out there.
It's the intangible things like warranties and customer service that make a brand stand out. It's good to know that if I ever won this card, and it failed 2 1/2 years from now, I would be sent a replacement.
