The unit that takes DDR maxes at 1G. So the speed for RDAM is not going to help Poser any?? I'm not building my own, I'm going to Dell. I can't lift a computer let alone put it together. Nor can I give it three years in house service. The Video card is 64MB DDR NVIDIA GeForce3 TI 200 Graphics Card with DVI (320-0289)It's $400 more for the Titanium Ge4. And so far, I have not heard much about it being necessary or even used for either Poser, Bryce or Vue, the only progs that are likely to be affected. I dont use Max or Lightwave and am not likely to. Ah well, it will all depend on whether the old--little over a year!-- puter has lost a Video card or a motherboard. If the latter, the new one gets loaded to the brim and has an extra firewire card if I can fit it in. I hope it hasn't. But if I have to buy a new Video for it-- I may have to go to 1G just budget wise. Normally I would rather high-end it all the way, but this is such a high end, that I thought I would get some advice. Emily
