THIS is one superbly researched, behind-the-scenes, whistle blower article. Wow. A window into the murky world of billion dollar CPU and graphics designs.
Personally, I am rooting for nVidia (thanks for the Linux support!). But, just last week I built a machine for virtualization - Quad X4 620, on a Gigabyte 785GS board with integrated ATI 4200 graphics. The price-to-power-to-power-consumption ration was just awesome.
AMD/ATI is in a nice position with their integrated chipsets - and the discrete ATI5870 is kicking ass.
But there is a new entry into the graphics arena - Imagination Technologies with the PowerVR core.
