Nvidia Geforce GTX 260m Vs. ATI HD Radeon 5850

[Pie]

I bought a alienware and i saw that the 260m was around 100$ more than the radeon 5850. I looked up some info on them and it says the 5850 is much better than the 260m. Would the 5850 run better on dolphin than a 260m?

ATI radeon 5850 is exponentially better than a gtx260m. Hell, even a gtx 8800 will beat 260m in most games. It's probably a mistake, or just a rip off.

the desktop 260 is slightly better, around the power of 5770/5830
