I'm looking for input, what would be the best way to optimize a computer to run LDD, and I mean to run LDD without any real lag or anything of the sort.

1. SSD.

2. Enough RAM to run 32 bit application. Some model may take up to 2 GB of it.

3. LDD version 4.3.8 is single-core. So CPU overlocking is a good idea. Many cores are not required yet.

4. I am using GeForce 660, and have no issues with it, but old videocards (like my 7-years old integrated intel on laptop) may work bad.

Some CPU like Intel 2700k overclocks into 5GHz fairly easily and that can be a boon for LDD. Some people have gotten over 8.5Ghz out of AMD FX but such overclock usually comes at a price like continuous liquid nitrogen supply.

Real men run a continuous stream of beaten eggs through their cooling system so there's a constant supply of scrambled eggs to eat.

LDD runs just perfectly for me, and I went a bit beyond what I needed for gaming only so that I could do Photoshop and the like as well: Core i5 4690k (seems to be the de facto processor for mid-to-high level rigs?), an SSD for the boot drive + programs (except for Steam games), an HDD for everything else (Steam games, files, video, etc.).

The only anomalies for a modern workstation at this point is the GTX970 graphics card, which I need for games:

...and the 32 gigabytes of RAM. I do make use of nearly all of it from time to time, as Photoshop will take as much as you'll give it.

If you're going to be building a general use computer, then go for something a bit more reasonable in terms of graphics cards, RAM, and processor spec, but the SSD + HDD is extremely useful because everything will load faster and you'll have the slower rust-spinner for big files and such.

Edit: LDD will run on something equivalent to a potato, or the average toaster, according to Brickipedia:

- OS can be Windows XP, Vista, 7, or 8 (and presumably 10, when it's released) as well as OS X 10.6.8 or higher for Macs.

- CPU can be anything 1GHz or higher.

- Graphics card has to have at least 128 MB of VRAM, and must be OpenGL 1.1 or higher compatible - or for Mac anything equivalent to the Geforce 5200 or Radeon 7500, or better.

- You need at least 512 MB of RAM for a Windows machine, and 1GB in a Mac.

- One GB of HDD space in both cases.

If you don't already have a computer in your house that meets these specs, I'd be surprised. I'm pretty sure the bare minimum nowadays is something like 4-8 GB of RAM. I also just checked Newegg and you can't buy a processor lower than 1GHz clock speed anymore (and I doubt half the ones that barely clear that clock speed will fit into a recent CPU socket).

Please don't spend a stupid large amount of money like I did on a computer, if it's only for LDD. My awful laptop runs it quite happily if I turn off GOOD graphics.

Currently LDD is just slow because the code were never optimized for multi-core CPU so it would run on even ancient Pentium 3 laptop I have (1GHz) Also it doesn't really take advantage of high end video card either. I am hoping this will be fixed when they make LDD 5 in the future, to use multi-core for connection computation and to leave complex rendering to high end video card.
