Diamond stuffs 1GB onto ATI Radeon HD 2900 XT

With leading-edge graphics cards getting more and more dedicated RAM shoved onto their PCBs, it's only surprising that it has taken this long for a 1GB single GPU card to hit the market. Diamond Multimedia has just announced the launch of its Radeon HD 2900 XT 1GB, which packs a full gigabyte of GDDR4 memory, second-generation unified shader architecture, 512-bit memory interface, integrated CrossFire scalability, and built-in HDMI support. Moreover, it also includes ATI's Avivo display technology, dual-link DVI output, HDCP compliance, and DirectX 10 support. No word just yet on what kind of premium you'll be expected to pay for this momentary claim of superiority, but we'd wait for the benchmarks to see if it's even worth the extra coin.
