Both cards should work, however at 4x AGP instead of 8x AGP.  Fortunately the performance difference between 4x and 8x is miniscule (very very very small).  That model Radeon card are you talking about?

The ATI is: ATI 9200SE 128 MB dual video...

And, do you mean 8X is worse???

Or what??

So an 8X will work in place of 4X?

Thanks mate!

PS- I have a 4550 Dimension, 512 ram, 2.66 GHz Intel Pentium 4.

8x AGP is worse than 4X AGP, performance wise they are very equal.  And yes, 8x AGP cards will work in a 4x AGP slot.

Will ATI work in the place of a NVidia though?

YanBooth,

Yes. Be sure to remove all reference to Nvidia with the driver remover, remove the card and then add the Ati card.
