Goodday elecow,
Today, a system for architecture can be very demanding of all the sub-systems > processing, RAM, graphics, and disk. At a certain level, quite modest systems will run 2D CAD very well, but the increasing demands of 3D, especially rendering and animation take more and more power.
The programs you listed are among the most demanding as you have 3D, rendering, high CPU intensive graphics processing in Adobe Cs, and so on. Even Sketchup is demanding. I have a quite fast Xeon E5 system that is running the first two cores at 3.8GHz, has 24GB RAM, and a Quadro 4000. On that system a Sketchup file over 40MB is almost unusable without careful tricks of turning off layers and navigating in monochrome. Fortunately, it seesm that in 3D CAD, the higher the software quality, the better it runs on ordinary systems, and both Autodesk and Adobe seem to do that well.
Overall, the best, long term solution for a CAD system is going to be LGA2011 or dual LGA2011, a Xeon processor or two, ECC error correcting RAM, and a workstation GPU that can run the special drivers that make viewports work. LGA2011 has a greater bandwidth, more PCIe lanes, more memory controllers, and other impressive jargon as well. As I say, AutoCad 2D is designed to run well on lower performance systems, and there are programs that run well on consumer / gaming cards, but if you're a student it's best to be prepared for anything and as well, try to have a system that can expand as the programs and work becomes more complex.
Follows is an idea for a system that intends to have a good all round capability for 2D and 3D. this is based on the Xeon E3 which are have very good cost /performance. Importantly, the Xeon E3 is hyperthreading whereas the i5 is not. The prices are in U.S.Cowbucks so I expect it would be more in Kangarands.

My suggestion is to the place the OS and Programmes in a partition, have a second partition for files, and a third to keep a system image.

Again, this is a bit generic system so as to accommodate most kinds of programs you might encounter.Sorry, this will be over your budget, but keep in mind that going a step up in the first place might save changing for a couple of years and be less expensive in the long term.
If the cost is very important, here is a way to have a good performance for a bit less. The AMD FX 8350 eight core has about the best cost / performance ratio of any CPU.
