ArchiTom,
I thought I sent this to you via PM, but it just disappeared into the ether apparently. It took me a little while to reconstruct it as I had to re-research parts of it. It was much more complicated than I'd anticipated with the pricing differentials in the U.K. and the fact that many of my assumptions about which components would suit your application were inaccurate. With 3DS Max, there are as many opinions about best builds as there are stars, particularly with the "proper" CPU and GPU. I started with LGA 2011 6-core processors and X79 boards with 64GB RAM. Many of the options were non-starters simply because of price. Then compatibility issues eliminated many more. I could go on and on, but the bottom line is when I dug into what "real" architects were using for real-world projects, I ended up ditching the whole build I had put together by that point. Funny though - when I got done, it looked a lot like a high-end gamer. I've checked it over a few times and can't find anything that I would change that would stay in budget (it's actually 22 pounds over, sorry). I'm sure the other denizens of THW will have lots to say when they see this, but as I said, it's the best that I can come up with. I would, however, recommend you vet this with any tech savvy architect friends - they might have some insights that I'm lacking. A nice side-benefit to the build coincidence is that if you decide to play games on it, it will really kick ass.
Here are some notes on the build:
1. You'll see a benefit to applying an overclock to the CPU (bumping the base clock to 4.2GHz should give you a tangible performance increase and you can take it to 4.4GHz easily), so I included an OC-capable board and aftermarket CPU cooler.
2. I left out any SSDs. If you want to add one (or two), it will significantly speed your load and transfer times, but it won't help in-program. 3D rendering is usually strenuous enough on the system that a 7200 RPM HDD shouldn't bottleneck performance.
3. The budget topped out at the 780 TI, albeit a very good one. If you can pry loose the cash, a Titan would be better.
4. You could save a little by getting a cheaper case, but the R4 is excellent - very easy to build in, cools well, and has excellent sound-reduction features. I have a secondary build in one and often have to check the power light to see if it's on. To improve cooling from stock, you'll want to remove the top internal drive bay. I would also recommend replacing the stock fans, but you can try it as is and add or replace fans as needed. I put two Noctua NF-A14 140mm fans in the front and two more in the rear and top/rear mounts. You won't need that many unless you add a second GPU, but two in the front and one in the rear would do nicely.
5. The optical drive is the cheapest reliable one I could find. You can dispense with it if you don't need it, or bump up the quality if you intend to use it more than occasionally.
6. There's only 32GB of DRAM - going to 64 would entail changing the mobo and CPU and increase the price by a large margin. From what I've read, 32GB should be fine for you.

Edit: I forgot to comment on the PSU. That EVGA model is a top-tier PSU with 80A on the 12+ rails - it'll run quiet and give you headroom for any component upgrades.
