This is a base upgrade from really terrible S3 onboard video. The power supply is weak so I'm looking at the 2400 but the machine will not be used with Vista (so Dx10 not an issue) and will not be used for HD Dvd's so the onboard DVD decoding not an issue.
I think they will be similar in fps in older games but would like to get some more input before I throw the 2400 in the machine. I have the 1550 I can use if it will be a significantly faster card.

2400HD imo
As you know they are both low end cards & although they may play some older games(possibly with lag) they will have a hard time with modern games (if they play at all). The HD 2400pro is the better of the pair in my opinion that is as I have never owned either card so...
