Which Radeon to buy?

Hello,

I have been looking for a new graphics card to replace my 3D Prophet 4500 with (Kyro2).

I have decided to buy a Radeon 9000 since I figured out I get more card for my money buying ati.

I found the perfect card on Sekvencia (a pc store) but then I noticed they have another card too, with the same price!

Sapphire GFX CARD 4X AGP Radeon 9000 128MB DDR + DVI + TV

Connect 3D GFX CARD 4X AGP Radeon 9000 128MB DDR + DVI + TV

and for 100kr more (10USD) I can get this 9100 card w/128MB Ram:

Which of these three cards should I buy?

Thanks,
Bjorne

this will help you decide, as you might/might not notice that the 9100 isn't rated...from everything that i have read, the 9100 isn't significantly faster thent he 9000
