|And considering that the screen is fairly low-res to support a fast response time, that extra 64MB isn't going to do much of anything in most games.
That's probably true on many games from the pre-DX9 class generation, that don't push the envelope, however Video RAM is used to cache geometry as well as texture data. When maxed out the card will have to fetch through AGP into system memory, which can be a throughput limiting factor.
Most of what I do is game/engine development with modelling as well so this becomes even more urgent than just as a game user.
That said I think you're right that it will not be a killer but certainly for a laptop in that range it seems to stick out that the extra 64MB is missing, I guess that's why Voodoo is working on it.
My question then is, will Voodoo allow you to upgrade that to 128, or is that cost prohibitive/technically impossible?
And as far as the Athlon 64bit goes, what's the benefit if you're running a 32bit OS on it? It seems that the benchmarks beat the fastest P4's by a small but still relevent percentage, but considering that these laptops max out at 2GB of ram, the true benefit of a 64bit OS (larger addressable memory space, i.e., greater than 4GB) seems lost.
