Being an AMD user, all I can report from is other's input and the problems that have come up. (1)The GeForce 4 card and VuePro get along very well, as long as you are aware that there is a -lot- of inconsistency with gamecard drivers and OpenGL implementation. I have the GF4-4400 and the latest Nvidia drivers, and VuePro handles OpenGL just fine. Your experience with what driver works best could vary, due to things like motherboard chipset and AGP driver, installation order of system drivers, etc. Once you have a good combination, be sure to save those driver versions so that you have them. (2)VuePro -is- coded to utilize hyperthreading, but this does =NOT= equate to two processors. It's a nice little hardware trick that allows more than one process thread to run by hijacking the pipelines in the processor that are not being used. Your OS may report that it -sees- two processors, but you only have one core there. And more importantly, you only have one L2 and L3 cache, one memory controller, and one set of linked DIMM slots. The dual chip motherboards perform so well due to the fact that each processor can be doing its thing, and not have to fight with another processor for memory bandwidth and cache space; hyperthreaded P4's have to share that one pool of resources between the multiple threads running, so it is not as good as a true dual board. There is benefit if everything is coded to use HT; (In that respect it is like MMX and 3DNOW! ; if your app doesn't use either, then there is no benefit in having those pipelines in the cpu; they just sit there), but you will not see the kind of performance that the ad copy hints you might.
