Here is a good budget card:
APOLLO ATI RADEON 9200SE 64MB DDR, DVI/TV-Out, 8X AGP, "Devil Monster 3
Newegg.com $39.50

Both the 5200 and 9200 are better choices than the MX series. If you are
going to do 'any' gaming at all, I would recommend the Radeon 9600Pro
which can be found for ~$110 and is the most bang for the buck you can buy
right now

Here is a guide I often recommend for choosing quality, inexpensive
components:

They also link to an excellent price search engine that may help you save
a few bucks:

.... as you can see, there is quite a range of prices on your choice of
motherboard with Zipzoomfly having the best price.
