Radeon Video Cards

Awhile back it was recommended that a SAPPHIRE 100196L Radeon X1950PRO 512MB would be a nice replacement for my old ATI Radeon X300 (PCI Express x16) for FS9. Although it was out of stock, I later found a Diamond Radeon 1950PRO512PCIE at TigerDirect.com for $179. I bookmarked it, deciding I didn't need it since I was looking for work. Well now, that one has disappeared as of today. No big deal since I'm still looking for work. Shows you my priorities. But eventually I would like to upgrade the card. I found another site for the Sapphire card, but $242.00 is unacceptable to me.
The reason for this thread is that there's a lot of cards under ATI using the Radeon name which confuses me:

Included in the list is the HIS Radeon X1950 Pro card:

http://www.tigerdirect.com/applications ... ICEGRABBER
Certainly, a lot less than the one Sapphire card I recently found, but I don't know if this one be a good match with my current system. I already know that I have to upgrade my PSU to 600 watts. It would also help if I took a peek under the hood to see if this will fit inside my case. Pretty crowded, but I as understand it, the video card in my system is the easiest thing to replace without tearing it apart.
Any suggestions would be helpful.
Thanks.
