[citation][nom]Marcus52[/nom]"When the Radeon HD 7970 launched at $550, it looked like a reasonable alternative to the GeForce GTX 590 and Radeon HD 6990. Both dual-GPU boards are measurably faster, but they’re also $700+, power-hungry, and in the case of the 6990, embarrassingly loud. Even still, the 7970's asking price is still pretty steep."I fail to see how a piece of equipment that can't do what it's supposed to replace makes it into something you would consider because the price is lower.If you need the power of the previous gen dual-GPU option, the 7970 won't fill that need, regardless of it's price. It's the best single-GPU now, no question, but it's not so much better than the GTX 580 that it makes up for a second GPU.Maybe you can't afford a Radeon 6990 or GTX 590, but you can afford a 7970 so you buy it instead. That's great, and you'll get better performance than any other single GPU option, especially if you overclock, but it still won't replace the previous gen dual-GPU option. It will still be a "pay less for less performance" option. Nothing wrong with that, just don't say it's some kind of replacement for something that gives more performance because the price is lower. Performance/dollar ratio won't get you 60fps when you needed 2 GPUs to get that in your particular application, period.Going by that philosophy, you might as well stick with the on-board graphics capability, because the added cost of that is - zero. You can't beat a performance/dollar cost when the cost is zero.[/citation]
For me, it'd be because the GTX 590 and 6990 weren't particularly attractive products, whether as a result of cooling, noise, or power use. The 7970 came closest to matching their *performance* without the same issues, though its noise is, admittedly, unattractive under load.
