Dell (DELL), Research In Motion (RIMM) Electronic Arts (ERTS), AMD (AMD), Yahoo (YHOO), Nvidia (NVDA) Drive Techs Higher

Wednesday was a good day for tech stocks, driven by Dell (NASDAQ:DELL), Research In Motion (NASDAQ:RIMM) Electronic Arts (NASDAQ:ERTS), AMD (NYSE:AMD), Yahoo (NASDAQ:YHOO) and Nvidia (NASDAQ:NVDA).

Dell's upward move was expected after it reported a surprisingly strong quarter. Nvidia jumped on expectations of its quarterly results which were reported after hours.

Research in Motion got a boost from Citigroup (NYSE:C), which upgraded the stock a couple of notches from "Sell" to "Buy."

Electronic Arts Inc. was driven by the promising pipeline revealed by CEO John Riccitiello at a Goldman Sachs conference. He said the company should gain market share on major rival Activision Blizzard Inc. (ATVI).

AMD and Yahoo seemed to rise with the broader tech sector, although the moves they made were strong. Hewlett-Packard Co. (HPQ) also ended the trading session solid.
