hahaha, fuck that expensive shit, just buy an fx8320 or fx8350 with a good water cooling
just checked the link>server>dual cpu>matrox>second hand
you must be fucking joking, actually
First, the cpu is used to do calculations on the meshes, that means, translation, rotation, scaling, modifiers, booleans, cutting, sculpting, everything like that is done on the cpu, depending on the software, some have multi-core cpu support, some don't.
For anything, except moving around millions of polys, super expensive modifiers and booleans and giant fluid simulations you don't need more than 1 8core cpu. So, unless you're gonna kitbash a 60+ million poly robot/spaceship/whatever, scult at 10 levels of subdiv or simulate the splitting of the red sea or the collective farts of the human race you don't need more than 1 8core amd fx8320/fx8350 with good water cooling.
Second, the gpu. Even if you have 10 million cpus under your belt, you won't be able to display that much information. If you don't have a modern gpu, those 10 million polys/smoke whatever, you're not gonna be able to display them even if you turn on all the magical pixies like vbos, backface culling, hardware instancing, etc. So, if you're on a budget, don't buy anything and just fuck off. You should've said what kind of modelling you want to do? Low-poly, faux-poly, game models, short animations, advertising, sculpting, retopology, vfx, exterior, interior, product visualization, environments, simulations, cad, model painting, texturing, what?
