New ATI Graphics card doesn't work properly

I recently purchased a new video card. My old video card (ATI Radeon XT 850) ran all my games perfectly but its incompatible with a lot of newer PC games.

My new card (ATI HD 4650) lets me play newer games perfectly but my favtorite older game suffers from degraded graphics are horrendous slowdown. I installed the drivers straight from the installation disc that my new card came with. I even tried different drivers from the ATI website.

I called ATI and I was told that older games are sometimes incompatible with some newer cards and that I might need older drivers. I have no idea what that means but I'm sure there are players with better PC's than I so I find that answer to be inaccurate or I'm misunderstanding something.
 
What OS are you running? 32 bit or 64?
Rest of the system specs?
What are the "older" games in question that suffer from poor performance?
 
I'm running Windows XP Media Center Edition. The name of the game is "Phantasy Star Universe" and the program is called "Windows Media Center" which is what I use to watch TV. Both the TV and game run terrible with the the new card.
 
They were compatible does not mean your Power supply is powerful enough to power the card.

That's what seems to be the issue here from your description.
 
I don't get how it is the PSU if he can play old games put not new games. If say every time he played a game it did this then it would make since. If he can play new games but not old games then it can't be the PSU.

Exactly. If your PSU can't handle it, it will simply overload. It won't "struggle" to perform properly, it will either work fine or blow up (not really blow up, but it will die i think)

It seems like a driver issue. Go to www.ati.com and download the latest Catalyst version (9.8) and see what comes of that. I recommend going into advanced mode and changing all the 3D settings to "application defined" as this usually results in better compatibility.
