SLI 9800 GT or 4850

Which is better, an SLI GeForce XFX 9800 GT 512 MB or Radeon HD 4850 512 MB, for ASUS P5N-E SLI motherboard.

According to me, it's the same thing; may be a slighter gain for 9800GT

On ASUS P5N-E SLI, the SLI graphics cards are forced to share 16 PCIe lanes, so when SLI is enabled the bus is divided effectively creating dual PCIe 8x slots rather than 16x slots. Therefore 4850 GS or 4870 is better.

HD 4850 seems to be more powerful to me. A 9800 GT is a corrected 8800 GT with a medium 3way SLI.
