I'm totally with 3dgeek, moving SW to 64-bit should be the priority for every developer out there in 3d land.
The RAM aspect is of course an issue, but not as big as you might think. Moving to 4gig didn't make my machines fly any faster, in fact the 2gig X2 is still able to handle everything I throw at it and is even a shade faster than the 4gig box. IMHO it's mainly about addressing larger packets of data to the CPU, especially where rendering is concerned............on this aspect alone LW9 [64] seems to be 300% quicker than LW9 [32]. So for Maxwell, just imagine a 12hr render cooking in 4...........what luxury.
