  1. The programs I mostly use are Matlab, Lumerical, and Comsol, but I'd listen to input from people who use other simulation programs that don't support GPU acceleration. Suppose money (and RAM) is unlimited. Should someone working in scientific simulations get a CPU with more cores or faster single core performance? fwiw, we have two servers in my lab: One running a TR1920x and one with a Xeon E5-1620. But it's not really fair to compare them, considering they're made 5 years apart...
  2. Neither. That is a bit complicated to explain and I'd rather not to because it's irrelevant to the question. The strangest thing is that I'm getting mixed answers for this one question...
  3. I know that switching modular PSU cables between different brands is bad, never do it, etc, but extensions are fine. I assume that the usual use case of extensions that you attach it at the end of the cable that came out of the box. My question is, can you do it the other way around? Suppose we have a PSU, say, the Corsair SF600 (because that's the one I plan to buy). It's modular, everything on the PSU itself is a bunch of female ports, and it comes with a bunch of male-to-male cables. Once you attach the PSU cables, you get a bunch of males that can connect to the components on the board/hard drive/GPU, etc. What if I attach a male-to-female cable on the PSU, and then attach the male-to-male cables that came with the PSU's packaging? Will that be as problematic as switching modular PSU cables between different brands? If that wasn't clear, here's a doodle: Usual modular PSU scenario: +----------+ +-------------+ | | | | | PSU O <- +------------------------------+ -> O component | | | (cable that came with PSU) | | +----------+ +-------------+ Usual modular PSU scenario with extension, I assume: +----------+ +-------------+ | | | | | PSU O <- +------------------------------+ -> O--------------+ -> O component | | | (cable that came with PSU) (extension) | | +----------+ +-------------+ What I want to do: +----------+ +-------------+ | | | | | PSU O <- +--------------O <- +------------------------------+ -> O component | | | (extension) (cable that came with PSU) | | +----------+ +-------------+ The cables in question here are the 8pin PCIe cables and SATA. I'm planning to get the extensions off AliExpress, btw. If there's a place to get better cables (ketchup and mustard cables are fine, nothing fancy) from a place that has international shipping, I'd love to hear about it.
  4. Relatively speaking, a lot. It's also under warranty for two more years. A brand new 1060 6gb goes for 1200 shekels without taxes, or 329 USD. A brand new 1070 (again, tax free) is twice that price. I'm getting this 1070 for 1000 shekels (274 usd). That's the price of a 1050Ti in my city (with tax). At least I only have to travel for 2 hours by train to get this one. Going to the tax-free zone means that I have to travel for 6 hours by bus to buy it. This one, it was the only SFX PSU I found in the country I was living in at the time. Planning to repurpose it for a mini-server at some point. Full system build. The actual case is a Jonsbo v2 but I have a PCIe extension cable. Buying a new case is not an option yet.
  5. I'm about to buy a miner's old 1070 but it turns out that my current PSU doesn't have the right connectors. My current CPU is a i5-6600k, no overclock, not planning to do OC. Location is Israel, budget is 74usd (so that I don't have to pay taxes). I can't find anything locally, so I'm buying on Amazon. I found a 450W Silverstone SFX (non-modular), but that's the only one I found. Maybe there's something else I missed? Thanks.
  6. Israel: http://ksp.co.il is one (pick Eilat in the branch list). There's a bigger search engine https://www.zap.co.il/ but I'm not sure if it works outside of the country. For Russia: https://market.yandex.ru/ is the best but it's only in Russian. I know that it's hard to generalize about brands, but my first laptop and tablet were both Acer, and both died after exactly 1 year and 1 month. They're very affordable, they're not bad products (for the price), but still.
  7. Will be used mostly for office stuff/LaTeX, remotely connecting to my work and home PCs, entertainment while I'm bored in planes and airports (needs long battery life), and last-minute presentation editing. I also like playing games from 2003. No smaller than 13". Touchscreen/stylus support and maybe LTE could be useful. Optional: if it can run some basic Comsol simulations (uses lots of RAM and CPU, no need for a good GPU), that'd be great. Budget: 1000-1300 USD Buying in either Israel, Russia, or Hong Kong, but I would prefer to buy in Israel for local warranty assurance. I also don't like Acer in particular.
