Get at least a 850 watt power supply. More power is always better then having to replace it if you add more things.
I think there is a slightly better video card but it is also in the 700 series.
Ssd drive? At least for the os and unity plus whatever modeling programs etc. Then at least one or two 1 tb hd for storage.
Totally up to you but I would really change the power supple. I have a corsair in mine and my sons. Runs without any issues.
Thanks for the input. So shave 16gb ram off and use that money for an SSD? Upgrade the PSU yes or no? The PSU is always an after thought for me, even though it’s pretty important.
If money isn’t issue, get a dual Xeon setup, having 2x CPU’s could come useful for baking light and stuff.
Better yet, just get a fully built workstation.
Samsung 840 Evo - 500gb minimum. I’ve got the 1TB version. 500 is cheap enough. This alone, is the single biggest productivity boost. Put your OS, work folder, the Sony stuff and Unity on it. Boom, 5-8 secs and it’s on device and I’m playtesting.
As these are the tools of the trade, you need fastest possible build times so you’re on device, you’re testing and working, not waiting.
Upgrade the PSU. You don’t want to have to rewire the whole PC in two years when you want to run SLI. It’s cheap, just do it. If you have to money get a better motherboard, you want to make sure your core components are good. Switching a CPU or GPU is easy, a motherboard is not.
I second better mobo(Asus), bigger/better PSU(750+), 16GB ram and Samsung SSD.
Another thing you should consider is noise levels, a noisy PC can cloud your head and make you lose focus.
So I recommend you make it silence with Antec P280 case, CPU watercooling kit, 120mm fans only and Asus FanXpert(part of Asus mobo). That’s what I got. My PC is almost dead silence and still runs really cool.
An SSD drive is definitely a great idea for every system. However, I strongly recommend the Samsung 840 Pro instead of the Evo. The Evo costs less, but it will wear out much sooner. Compare the P/E cycles of both drives. The Pro series has three times the P/E cycles compared to the Evo series. Here is an article about endurance of the different SSD drives. http://www.anandtech.com/show/6459/samsung-ssd-840-testing-the-endurance-of-tlc-nand
You’re spending > 500 for a CPU and memory and < 50 for the PSU that prevents deadly power surges.
I’d start in this range. Believe it or not, a good PSU is worthwhile to invest in, and keeping a good spacer between the current and max load will reduce the chance of blowing caps.
