There are two HP Pavilion laptops with almost exactly the same specs, except one has:

Intel® Celeron® M Processor 420
* 1.60 GHz, Level 2 cache 1 MB, 533 MHz Bus speed
* Intel® Graphics Media Accelerator 950

And the other has:

Mobile AMD Sempron™ Processor 3400+
* Level 2 cache 256 KB, Up to 1600 MHz system bus running at AC/DC Mode 25 Watt
* NVIDIA® GeForce™ Go 6150

I've read that the 6150 is a much better integrated graphics option, but can't find any direct comparisons between the 420 and 3400, so that I can decide which processor is better.

Which processor and graphics card combination would you choose?

I have absolutely no faith in the anything Celeron, so if I had to go for one of those, I would go for the AMD.

AMD ftw... due to the fact that if you do play any form of 3d games that intel graphics accelerator won't do shit for bricks
