A year after support thread started no solution on the horizon
Some owners of early 2009 model iMacs that have upgraded to later versions of Snow Leopard, Lion or Mountain Lion have been reporting issues with the included Nvidia GeForce GT 130 video card without a response from Apple, according to a year-long support thread on the company's support website. The issue appears to center around a faulty kernel extension released late in the Snow Leopard updates that remains unfixed, and causes graphic glitches, crashes and even kernel panics when the graphics card is stressed, such as during games.
Card overclocks graphics cores
ASUS is currently showing its upcoming Matrix GTX 580 Platinum graphics card, an overclocked variant of the standard GTX 580. Although the company has yet to detail its flagship Mars II edition, the Platinum model will provide 1.5GB of GDDR5 VRAM, 512 CUDA cores, and a GPU core frequency pushed to 816 MHz.
ATI Radeon HD 4890 GPU
AMD on Thursday morning further expanded its "Dragon" desktop platform with the introduction of the ATI Radeon HD 4890 graphics card, featuring 1.36 TeraFLOPs of computing power, faster GDDR5 memory, and engine clock speeds capable of nearly 1GHz. The GPU card offers support for DirectX 10.1 titles, including Ubisoft’s Tom Clancy’s H.A.W.X., Electronic Art’s BattleForge and SEGA’s Stormrise released last month, as well as GSC Gameworld’s S.T.A.L.K.E.R: Clear Sky. According to the company, the new graphics card is not only designed to provide exceptional value to OEMs and channel partners but also to do-it-yourself (DIY) consumers.
