Hi,I'm looking to upgrade my graphics card for my Gateway SX2800-01 with a high def 23" Gateway LCD monitor running 1920x1080.I want to do this to play Secondlife and run it as high as possible,graphics and frame rate,and to reduce lag and minimize packet loss.The closest I've found for a low profile card to do this is the"Sparkle-Geforce 9600 GT low profile".Is this a good option for Secondlife,and is it well suited for my computer? One concern being power supply.I have no problem upgrading power supply if thats needed and/or possible with this model.I'm pretty sure the current power supply is around 250w.And what about the difference between manufacturers Sparkle and Zotac?I've done some research but I'm not real knowledgable on the tech side of computers.This card seemed to be about the best for my needs,available slim line tower space,and price range.Any advice I can get would greatly appreciated.Thanks for your help.
