most ubuntu user switch from Windows a long time ago . my son who love to watch you Tube decimate three new Seagate hardrive before realize the extensive damage that can be do by virus and spyware run under a Windows xp platform . in the last three year since switch to ubuntu , he have only have one crash which merely wipe out he Open Office suite which be now not support by ubuntu . everthing else work with the exception of the Open Office suite . when the newest ubuntu release 11.04 come out , I imagine that it would be a upgrade that solve all the old problem . however , with the improvement and newer program and feature come additional hardware requirement , in my particular situation , a video card upgrade . try to run ubuntu 11.04 or even 10.4 with any less than 256mb of video memory bring forth either a error message that you input be not support or worst yet that you screen load up only to find that it be fill with green and red vertical line on the desktop . in addition , when you attempt to move you mouse , you end up with quarter inch wide mouse trail . those who have have this unpleasant experience will know what I be talk about . anyhow , ubuntu support recommend video ram no less than 256mb . I buy this 512mb card instead hope that more be both safer and better . I install this card in five minute and astonishingly my son 's computer come back to life in glorious and magnificent color . it be a wonderful sight to behold . Everything work and run well . Ubuntu user , wake up and take note that a ATI 8mb video card will not cut it . also note that this 512mb card have a Nvidia chip which be highly recommend by ubuntu support . thanks again to Jesse for you helpful comment & recommend this 512mb video card .
