Umm, isnt that a gossip page? I do not think i would be taken seriously there and do not want to cause another flame war just to be referred as but the op asked....
4550 is dirt cheap but might be for a reason. I am trying to disciple some info from googling/PassMark charts but there are way too many low end options. The last time ive made a pc with low profile card was about two years ago and 8600GT was a clear winner. I have no idea which is the best now.
