We've been looking at a few variants of the 5 series ATI cards lately. Today is no different. Except it is, otherwise we wouldn't be reviewing something we have before.If you plan to ever water-cool your graphics card then most of the high-end variants aren't any good because they use non-reference circuit-boards that mean you can't use an "off-the-shelf" water-block.Of course you can go with the reference designs which enable easy water-cooling, but then you lose the many other benefits such as factory overclocking, more stable voltages or whatever.If only it was possible to combine the extra cooling power of a non-stock cooler, with the ability to upgrade to water at some point in the future.Hello Asus, and the EAH5870 V2.
