Just finished setting up my pc with Windows 7 and was wondering if its time to upgrade my vid card to take advantage of Directx 11. I'm running an HD3870 which is a DX10 card and was wondering what I can expect in terms of performance for a non gamer. I've seen clips on youtube showing how DX11 improves game graphics but for someone who watches vids(youtube, avi, mp4, etc) and does general internet stuff, is it worthwhile to upgrade? I'm considering a HD5750 card and know that it will certainly have a higher performance than my old card but its the DX11 issue I'm curious about. Will I notice any differences in things like my desktop, icons, folders and such? Thanks.
