OK ,well first of all integrated video is the absolute the crap of the crap.
So choose your poison.
I'll start cheap and med performance,and go to the high end
Nvidia based cards.....run a little cooler and have a little less power requirements than Ati cards.
1. 7600gt...130.00$
2 7900 gs....160.00$
3. 7900gt or 7950gt..... 210.00$ depends on memory size
4. skip the 7900gtx and go to a 8800gts 320mb 275.00$
5. 8800gts 640mb version... I think you will need a faster cpu for this one. 380.00$
6. 8000gtx ..... forget about it!!..... 500.00$ plus
Ati based cards. and there Nvidia eqivalent. Prices are also similar.
1. 1650xt = 7600gt
2. 1950gt = 7900gs
3. 1950 pro =7950gt
4. 1950xt = 8800gts 320mb
5. 1950xtx = somewhere in between a 8800gts 320 and 8800gts 640. Price and performance. I think you'll need a faster cpu for this one to.
To play most games at 1280x1024 with med/high setting you need a 7950gt/1950pro.
What are you looking for?

Edit: This is a spectacular deal on the x1950xt for 219.00$ plus a 20.00$ rebate =199.00$
The card is has duel slot cooling so it will exhaust hot air out of your Compaq case.
This card will play anything your kids want for a year at least. Make sure you have a 450 watt power supply and a 30 amp 12v+ rail.
Heres a little read for the card
