I am not sure that it would be a good choice but you could take the risk of getting a GTS450 low profile (yes there is one) but it looks like a big candy bare but people have complained about the thermals and noise but its the best LP card out there. If it is for basic like video ect then you can look at a low cost 5450 LP which will blow your old 2400 pro away and I used to have one my self. Its the most stable ati card that I ever had except for my first encounter with drivers.
