PC Equivalent on 6-Core Mac Pro 2010

Hello,

First post so be gentle ;)

I have been a mac user for 10 years and I am currently on the look out for a new machine/second hand. I currently use a mac pro 3.1 and I was looking at a 6-core 2010 Mac Pro 3.06Ghz with 32Gb RAM.

This is going to cost me at very best £650 but I not opposed to a PC alternative if it meant i could save £££. The main purpose the machine will be used for is motion graphics, so After Effects, Cinema 4D, Premier, Photoshop and Illustrator. I do occasionally game as well.

So my question what would be an equivalent machine. I am fairly knowlegable on graphics cards so I have an idea of what i want to aim for in that respect but past that, looking at PC's seems like a minefield. any help would be very much apretiated.

heres one I have found that I think may be up to the task, but tell me if im wrong -

cheers

The graphics card in that thing is really weak so you are mostly paying for the CPU. The CPU itself is up for the workstation type tasks but its gonna crumble in graphically demanding games.

I don't know if any of those programs do GPU accelerated work but my recommendation is that you try to find a PC with at least a GTX 960 or R9 380 (The R9 380 doesnt support CUDA but performs better in games) in it for GPU.

See if you can find a place where you can select the parts and they'll build and ship it to you.
