Re: 5200 Go with 64 Megs Vs 5650 Go w 128 Megs
Go for the upgrade. Two reasons:
5200 is NV34M and the 5650 is a NV31M refresh. The original 31M gives better performance than NV34M for power, for quality, and for pure bandwidth. The NV31M 5650 refresh is even better yet. I'm familiar with the raw specs; I wrote the NV18M/31M/34M/36M mobile design guides at NVIDIA in 2003.
Maximizing the a laptop at purchase is ALWAYS worth it; you can't change your mind later.
I used to drive a Heisenberg, but whenever I'd glance at the speedometer, I'd get lost.
