Besides the fact that everyone's buzzing about ATI's 5xxx cards, whenever I hear someone talk about a high-end NVIDIA card they may be getting, it's always a GTX 260 216 or a GTX 285, and then they're always clueless when they want something in between.
Was the GTX 275 really that rare and unknown of a card?
I've only seen a couple topics here or the New System Build topic that involve GTX 275s. (In the last couple months, nearly)
The GTX 275 wasn't out very long before the 5000 series came and stole its thunder. It launched mid-April and I believe everyone was already getting excited about the 5000 series by that point. If I had to pick an Nvidia card, that'd be on my short list.
It had a peculiar, almost non-significance to it. The price point was wrong, performance was too close to some of their own less expensive offerings. Not a bad card by any stretch but just a badly timed/placed product.
