I run a sapphire X1950 pro 512mb DDR3 AGP next up is the HD3850 agp I believe it is called but it has driver issue's on alotta things and I still stick with the X1950 pro.
if your going to run the sapphire X1950 pro I suggest a corsair 550-VX PSU wich I also run there a power hungry card and no cheapo PSU's are going to cut it with them cards as I learned the hard way already.
the PSU I got off newegg for around $80.00 shipped new the card sells from $35.00-$100.00 used on ebay.
I paid around $100.00 about 2 years ago for a used X1950 there still a nice card though I ran bioshock without any problem at 1080P running on a athlon 4000+ overclocked to 2.7gig with 2 gig pc3200 duel channel ram kit.
I still use the same rig for gaming today and it gets it done
