Help with upgrade compatability

Hi,

I have got 3 old compaq evo computers from work free.

They look like they are currently P1.4, agp 1.5v & pc133

I was considering a cheap upgrade of these, as I know they are dated, basically for world of warcraft for the kids (& some other games/net stuff)

a) Palit 7300gt Sonic DDR3 AGP card, and (AUD $132)

b) 2 x 512mb PC133 generic ram (AUD $65 each)

This allows me to do all 3 for less $250 each

I'd like to know from the brains trust that is THG Formuz, will this work ok or can you recommend an alternative configuration.

Thanks all
