Quote: "Well, that was before Gigabyte got its hands on a couple GTX 285's and decided to push them even further, creating the Gigabyte GV-N285OC-2GI videocard. While the stock nVidia Geforce GTX 285 has a core clock speed of 648MHz, Gigabyte has pushed the GV-N285OC-2GI to 660MHz. Shaders have been ramped up from 1476MHz up to 1504MHz, and the memory capacity has doubled. The Gigabyte GV-N285OC-2GI has a staggering 2GB of GDDR3 memory running at 2400MHz! The Gigabyte GV-N285OC-2GI is a beast of a videocard, designed to not only compete with the Radeon HD 4890, but crush it outright. Cry havoc and let slip the dogs of war, indeed."

Quote: "The G92 core has been around for a while now with Nvidia utilising the GPU in a number of different cards making sure to keep renaming though so as give the illusion of a new product altogether. The core has evolved from the 8800GT to the 9800GTX+ right up to the GTS 250. This latest card uses a 55nm process tapping into both the heat and power consumption reductions combined with decent overclocking scope. So, as Zotac are prone to doing, they took the original GTS 250, used their overclocking prowess and came up with a new revision – the GTS 250 AMP! The shader, core and memory clocks have all been increased to extract maximal performance and so with any luck we should have a card that can deliver a similar price vs. performance ratio as ATI's 4850 and 4870 offerings. Let's see what it can do."
Quote: "Today, Asus has claimed that is has perfected the Radeon HD 4890 and the RV790 GPU, with a custom-designed videocard that it calls the EAH4890 TOP. The EAH4890 TOP has everything you'd expect from a reference Radeon HD 4890: the GPU and shaders are clocked at 850MHz and accompanied by 1GB of GDDR5 memory that runs at an effective speed of 3.9GHz (975MHz quad-pumped). Where the Asus EAH4890 TOP differs is in its construction. Asus has made dramatic changes from AMD's reference Radeon HD 4890, with a re-designed PCB, new power management, an improved heatsink, and more powerful air cooling. The result is a videocard that holds a lot of promise for some extreme overclocking and tweaking."
Quote: Today AMD launches their new Radeon HD 5800 Series of graphics cards. They are powered by a brand new graphics processor called "Cypress". Our review goes into all the detail about the new HD 5870 flagship, but we also have HD 5850 scores so you can get an idea what to expect.
