I dunno that's a tremendously huge number of 1976 Toyota Corona years.

Well except that I also brazenly suggest infinity is prime so no factoring is required for it.

Or maybe we could stop at 999,999,999 .... until then anyway. HAHA

My rough math tells me it will take about 20 Million GhzDays to TF all remaining exponents above 30,000,000 to 70 Bits

My 1 and only GPU could do this in just over 100 years....I am giving the collective 10 years...and that's not even taking into account Moore's Law.

Mind you neither is it considering that the vast majority of the GPUs are working on the GPU72 project....going much deeper than 70 bits on a relatively small range (the leading edges).

It would be possible to really get *all* exponents factored up to 2^70 - I can tell you that every number bigger than 2^p-1 for p>2^69 really has no factor below 2^70. But since mersenne.ca only goes to Exponents up to 2^32 I think that is a little too far off.

Well, I am planning on adding a GPU or two in the coming months. I'll see what looks good when it comes out. 1080p monitors are going somewhat out of style and I'm debating between 1440p 144hz and 4K. My space isn't suited for two or three monitors (I can't wait...) but that's a consideration, too.

What??? Are GPUs supposed to be connected to monitors?
How come? I thought they were just factoring machines...

I "implied" or intended to imply without actually stating that I am referring to *all* exponents on PrimeNet (<= 999,999,999)

My space isn't suited for two or three monitors (I can't wait...) but that's a consideration, too.

I've been using a 27" 1440p monitor for about two years at work and at home.

At work, it's great, but I think 4K would be better so I could make the fonts smaller and see more (I could easily read 4 pt font at 2 feet if my monitor were capable of legibly reproducing it). I've found having a single 1440p monitor is vastly better than dual 1080's, because the vertical resolution is useful for code and documents, as is horizontal resolution for looking at spreadsheets and databases with many columns without monitor bevel in between. I'd go with a high quality 4k monitor now, but 1440p is excellent for work.

At home, I've found the 1440p format somewhat awkward. If you're watching a 1080p video, it doesn't leave much useful space for doing much else. If you maximize the video, the scaling isn't as simple as pixel doubling and looks odd. If you consume a lot of video, I would highly recommend going 4k at home and skipping 1440p. I'm not really a gamer so I can't comment on that.

TheMawn · 2015-03-06, 04:49

The 1080p scaling is something I had not thought about. I'll have to give it some thought and see what the market is up to when I get there.

1440p offers a high refresh rate which would be ideal for "competitive" gaming, where 4K is unable to support 120hz for the time being. 4K offers better real estate and therefore is better for productivity and non-competitive games (the likes of Skyrim).

I have always liked the idea of multiple monitors though I have only occasionally had the chance to enjoy it. Some part of me really wants the monitors to be the same but I suppose if my financial situation allowed it, I could have one of each? Move things around as desired. On the other hand, my CDO (the letters should be in alphabetical order, damnit) would probably prefer two identical monitors.

Decisions...

Why the quotes around competitive?
