Hey all,
Getting ready to purchase CFD desktop, was looking for some comments/criticism. Primary use is OpenFOAM, with some pre/post processing. May throw on AutoCAD in a few months, if Windows is installed alongside Ubuntu. Parts list is available at: http://ca.pcpartpicker.com/p/JcQNbv Summary is: CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor Motherboard: Asus X99-A/USB 3.1 ATX LGA2011-3 Motherboard Memory: G.Skill Ripjaws 4 series 32GB (4 x 8GB) DDR4-2800 Storage: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive Video Card: Asus GeForce GTX 950 2GB Video Card Power Supply: EVGA 500W 80+ Certified ATX Power Supply I have a monitor/keyboard/mouse/1TB HDD/thermal compound that I can use, so dont need to buy those. What do you think? |

Looks reasonable.
But since you asked for thoughts, here are mine Depending on how much you want to overclock the CPU and how noise-sensitive you are, a better cooler for the CPU might be needed. Same thing for the power supply. An extra fan for the case might also be a good idea. For the video card: I don't know if the GTX 950 has any specific features you need. In terms of performance, a GTX 750 TI with 2 GB VRAM will get the job done for a lower price. |

Quick update for anyone interested,
Computer runs great, been using MPPICFoam/Goldschmidt tutorial as a benchmark. Solves in 16.5 minutes after tweaking. Turned off hyperthreading, overclocked to 4500 MHz. When running, temperatures are around 60 +/- 5C, brief peaks at 75C. Quiet and stable operation suitable for an office. Although I didnt make any changes to the original build, the decrease from 950 to 750 TI seems like a reasonable cost-saving choice. |
