Nvidia (NASDAQ:NVDA) drops 3.3% AH after warning it expects FQ4 (ends Jan. 29) revenue of $950M, plus or minus 1%, below a Street consensus of $1.06B. Nvidia blames the hard drive shortages and price hikes caused by Thai flooding, and a decline in sales for the Tegra 2 (used in many high-end Android tablets). Archrival AMD just reported weak sales for its PC graphics chip business.
