PowerColor Radeon HD 6870X2 Graphics Card Review
 

The PowerColor Radeon HD 6870X2 is a unique product that delivers high performance. Despite some minor problems with the minimal speed, the dual-processor card from PowerColor left no chance to the Nvidia GeForce GTX 580 in our tests. Most importantly, the PowerColor Radeon HD 6870X2 costs as much as reference GeForce GTX 580s and is expected to get even cheaper eventually. The card's cooling system, even though not perfect, copes with its job with less noise than the GTX 580's reference cooler. Besides, the Lucid HydraLogix chip allows combining the PowerColor card with any Nvidia-based product into a single subsystem to get even higher performance. Added to that are awesome accessories, nice-looking packaging and a 2-year warranty.

We can note that two reference AMD Radeon HD 6870s are going to cost you no more than $360 today, yet they would require a mainboard with two fully-functional PCI Express x16 slots (which are unavailable on the popular LGA1155 platform). They would need more power cables and would produce more noise. So, the PowerColor Radeon HD 6870X2 is quite a competitive product and we are now waiting for Nvidia's response like a dual-chip GeForce GTX 560 Ti “X2” priced at about $400 and equipped with a low-noise cooler. It might be yet another bestseller if it ever comes out.
