Maybe I'm missing it, but where? I've seen limited 2gb pairs for $50 on sale in the past week or so, but I could have swore that this was the normal price this summer. Most I see is still in the $70-80 range for 4gb. Even the deal I got from newegg went up to $60 the next week.

Newegg is showing 1x4GB chips fro 50 bucks a pop most with free shipping.

I don't think using that thing would be worth it unless you are on a strict poor person budget. I was there for many years, so from that perspective the 6 dollar upgrade for 25 percent cpu performance that you're probably getting is worth it, but if you have a bit of spending money, then you can get huge performance gains from the cheapest of modern Intel chips and boards. Keep in mind that any new stuff you buy will be more reliable and covered by warranty. Not to mention that the thing probably sucks up 5 times the juice of a modern chip.

what F^2 said, jitter is a real phenomenon but it isn't very significant for digital audio in 99% of cases.

But really I'm posting this because those random noises you hear when starting up a high CPU task? May not be what you think. CPUs get their power from switch-mode regulators. Switchers have magnetic coil inductors, which can mechanically flex a teeny little bit as the electric current flowing through them changes. And that current is changing; modern CPUs tend to rapidly switch between lots of current and none when they're not fully loaded. These switching events may sometimes happen at audible frequencies...

In other words sometimes it is possible to hear noises emanating from components on your motherboard rather than your speakers, if the room's quiet and there's nothing else masking the sound.

Certain nVidia 970's were doing that pretty bad.

I had mine up to 4.6 with one.

We've been talking about CPU throttling games, my favorite is World of Tanks! I had a wacky crash or something one day and didn't load the right BIOS profile. My 2550k (2500k sans igpu) was at stock clocks and I was blown away! Game was running so terribly I thought my computer was broken! Cranked it back up and it runs great!

You're assuming a perfectly distributed load. You can't just parallelize a game into equal threads like you can with 3d and video.

Here's an example game's threads:

Main thread
AI
Physics
Sound

So it is 4 different threads, but they are not equal. Another job might be decompressing files or talking to the network. They're just not all going to be going at full speed all the time. Having 2c/4 might allow you to squeeze in a smaller job without needing the power of an entire extra core. Like another said, the "small improvement" that the difference gives you is enough to tip the scale from unplayable to playable.

What a crazy straw man argument. Why did you type all that? Yes, some people here have been unreasonably on one side of that silly argument or the other. On the whole though, I think we have a pretty nuanced view of the pressures, both profit and physics wise.

It's interesting, the consoles have 8 cores, but even the new scorpio in the xbox is otherwise anemic in the horsepower department in terms of single threaded performance. 2.3ghz not jaguar , not ryzen isn't impressive. (Though it is running GDDR5 RAM)
On the other hand the graphics are what, ten times more powerful?

I guess what I really want to know is when I can get graphics memory for my pc's processor.

Does anyone remember that article that showed that RAM frequency was important for frametime consistency on Intel CPUs from the last few years? I think it at least covered Sandy bridge through haswell, and basically demolished the old "ram frequency doesn't matter at all" mantra that was common for a long time. Was written about one or two years ago iirc

RAM is not worth upgrading. Increasing your turbo boost (overclocking) certainly is.

My opinion on RAM comes from my experience going from 1600 to 2133 with my 2500k. If my processor is not OC'd up to 4.5ghz where it should be it seems like the computer is broken. I tried the faster RAM speed, my motherboard only got it stable at 1866 and honestly I can't tell the difference. It is SO lost in the noise of SSD's, graphics card upgrades and the aforementioned overclock.

I play games like Rocket League, World of Tanks, DOOM, X-COM 2 and they all run great at over 100fps at 1440p. (except x-com 2, duh).

I attempted to go two up, but my six year old board wasn't having it. It's not going to be a big noticable jump even if you get results like the digital foundry article. Maybe certain specific titles, and it's a lot of money for single digit performance increases. I think I made clear that I was offering anecdotal evidence as well.

What's your point? Amazon ran a deficit for years, so maybe he's more of a Bezos, except, he's beating Bezos (and ULA, and Russia) with his rocket company.

For certain tasks the threading can be very advantageous, but for our purposes, the higher single threaded bandwidth is probably going to give better high end performance.
