"The ASUS ENGTX480-2D1-1536 videocard stays pretty close to NVIDIA's reference design, with a 700MHz core clock speed, 1.5GB of GDDR5 memory clocked at 924MHz (quad-pumped to an effective 3696MHz) and a 384-bit wide memory bus. Here's what the little beastie looks like under all that heatsink - a very large GPU surrounded by twelve BGA DRAM memory chips."
