Hi Pam. Ive just ordered a new pc with win7 hp and 12 gb of ram to get back into this. Am i wasting my money?
Depends what you intend to do with your computer besides Bryce.
Bryce 7.1 Pro can use up to 8 cores / real and virtual.
There is not special advantage in having a fancy graphics card, although having two minors is very helpful for other reasons.
Making Bryce large address aware will let it address up to 3 gb of memory. But you will need some for your OS and you might want plenty of memory for other reasons.
This is my system specifications - I use Bryce quite a bit and have no real issues with this setup.
Windows 7 Pro
64 bit OS
Intel i7 CPU
6 Gb memory
HD 5850 GPU
Edit. Rendering, which is ultimately what Bryce does is dependent entirely on CPU grunt and specifically floating point number crunching capability. Which is why I chose an i7 920 processor - in terms of games performance this was not as good as an equivalently priced AMD but… i7 does crunch numbers slightly better in the benchmarking, the i7 has four real cores and four virtual cores via hyper-threading technology. The HT cores do not perform as well as a real core, it’s just a thread processing trick used to shuffle the instruction processing around for better efficiency on chip. Whatever you do though, if you intend to be mostly rendering, is make sure your system is well cooled. Rendering works the system harder than high end video games - for example - since they farm off some of their load to the GPU. Expected load from a game would be 80% for rendering at high priority 100%. It makes a difference.
