New videocard comparison: 9800Pro to 6800GS..

Ah, the ageold question of Nvidia vs ATI

I've been an ATI fan forever now, and I'm getting a couple new peices of hardware, one of which is my video card. I need to upgrade to PCI-E, and I found this card for $225 CAD...

I have a 9800 Pro 128MB AGP right now, and I couldn't find comparisons on tomshardware.com or anywhere else about how these 2 might compare against eachother. I'd imagine the Nvidia would outperform the 9800 Pro, but does anyone know by how much?

Thanks!
