Apple created two versions of the logic board. One with a NVIDIA GeForce 9400M graphics processor that shares memory with the system or an ATI Radeon HD 4670 with 256 MB of dedicated GDDR3 memory. The ATI Radeon HD 4670 would be a better logic board to get. iMac Intel 21.5' EMC 2308. Specifically, Apple reports that the MacBook 'Core 2 Duo' 2.4 13' (Unibody)- with the NVIDIA GeForce 9400M with 256 MB of memory shared with the system - is between 2.5x and 6.2x faster than the MacBook 'Core 2 Duo' 2.4 13' (Black)- with the Intel GMA X3100 with 144 MB of memory shared with the system - running tests in Unreal Tournament.

At just 0.95 inch thin and 4.5 pounds,2 MacBook is truly the next generation of notebooks. 1Testing conducted by Apple in October 2008 using preproduction 2.4GHz Intel Core 2 Duo–based MacBook units with NVIDIA GeForce 9400M.
I experience a similar problem, until now not a single Nvidia driver works for my setup: same Macbook as OP: Early 2009 Macbook White 13' with Nvidia 9400M graphics card.
If I let Windows Update install the 341.71 driver upon restart I get into a bootloop and the machine would not even get to the log-in screen - it crashes before that, right after the windows boot logo. The same happens with the newer Nvidia driver 341.81 downloaded from nvidia.com ... any hint / tip would be greatly appreciated!
