In that case,get the i7 and reuse some of the parts you have and upgrade those with time.
i7 3770k -19k
Gigabyte Z77X UD3H -12k or Asrock Z77 Extreme6 -12k
G.Skill RipjawsX 8GB(F3-12800CL10S-8GBXL) -3.6k
Corsair GS500 -4k
NZXT source 210 elite - 3.2k (2.6+0.6)
CM Hyper 212 evo -2k
Buy another RAM stick later if you require it.i7 3770k can get quite hot especially in summer,hyper 212 evo would keep the temperatures down and also be helpful for overclocking.For the things you have mentioned the i7 3770k is overall a much better processor than fx8350.Grasshopper and Rhino5 are primarily single threaded even though rhino5 has now support for multi-threading.3ds max 2013 is also quite faster on i7 3770k.In some applications while rendering the fx8350 can come close but mostly i7 3770k comes out ahead clearly in most scenarios and also has much better single/light threaded performance.Single/light threaded performance is important as many other things like previewing the model are generally single threaded and in some cases are dependent on GPU.For graphic card check out both firepro and quadro cards.
