[QUOTE=nikomo;42703807]1980s called, they want their aspect ratio back.
Pretty sure they don't make anything with that aspect ratio in decent quantities anymore, let alone with HDMI.[/QUOTE]
Gee.
[QUOTE=woolio1;42705130]Except they do. They're just 17" and under.[/QUOTE]
And that's perfect. Just not having luck finding one.
[editline]Oh my...[/editline]
Checking on eBay, there's not much choices and they're $150+ for a 9.7"er and they all seem to be special use (like "field monitors"). Maybe I should bother with a converter to DVI instead of direct to HDMI.
Is there a way to speed my hard drive up? I just got an i5 and it is really slowing my computer down.
[QUOTE=wilson23;42716419]Is there a way to speed my hard drive up? I just got an i5 and it is really slowing my computer down.[/QUOTE]not really. Defrag regularly and cache things in ram.

Only thing you can do is defragment it, and all that does is fix any filesystem fragmentation that could be slowing it down, it doesn't make it faster than it was new. There's no way to "overclock" a hard drive.
If it's really too slow, just get a new one, or an SSD.

[QUOTE=gman003-main;42722042]What?[/QUOTE]
We need computer facts.
Explain rotational velocidensity to us.
So I'm back with my HDD problem, I opened my case on boot and I have now discovered it's either the HDD or D drive making the rattling/crattling sound.
I Googled a bit and I haven't found anything saying that this particular noise is a problem, but I am still concerned since it seems weird paying $1700 for a PC and not make sure it's quiet.
It's mostly on boot it's noisy, then it comes in waves over some time and after like about 10-15 minutes after it's booted it makes no sound at all almost. (By almost I mean it of course makes a sound when opening programs or something, but not loudly).
Is this something to be concerned about?
Footnote: Last time I asked this question someone told me to scan my HDD and it said no problems what'so'ever in there. But I don't know if that software can really REALLY tell if something is indeed wrong here, I guess I'm just paranoid that something is broken :suicide:
Yes. Your hard drive is experiencing mechanical failure. Back it up, send it in for a replacement. You're still under warranty, yes?
[QUOTE=woolio1;42722225]Yes. Your hard drive is experiencing mechanical failure. Back it up, send it in for a replacement. You're still under warranty, yes?[/QUOTE]
It should be, I forgot I recorded the sound so if you [URL="https://dl.dropboxusercontent.com/u/82299943/PC%20sound.m4a"]wanna hear it before I take it to the fabric[/URL] that's an option.
It's an M4A file, silly iPhone.

Explain rotational velocidensity to us.[/QUOTE]
Well, rotational velocidensity is simply the density of information as expressed in units of rotational velocity. This is mainly for things like hard drives - a 2TB hard drive spinning at 5400RPM would have a rotational velocidensity of 370MB/RPM or so. This is why a larger-capacity hard drive with the same RPM as another will have a higher read/write speed.
Now, this can obviously be extended to optical (ie. CDs, DVDs, HD-DVDs, Blu-Rays) and magnetic media (ie. floppies). What may be less obvious is that this can apply to flash drives as well.
See, flash drives store data using electrons, trapped inside a floating-gate transistor. Electrons, being a fermion, have a quantum spin of a half-integer value - for electrons, 1/2. Therefore the precise rotational velocidensity of an SSD depends on how many charge states it has - for SLC, you get 2/2=1RPM, for MLC you get 4/2=2RPM, and for TLC you get 8/2=4RPM. Expanding that to the entire drive gives you rotational velocidensities of 3.84GB/RPM just for a 120GB drive - no wonder SSDs are so much faster!
But wait! This isn't normal spin, this is a quantum spin. Therefore the actual result is a complex number - although for practical purposes the real component is negligible and can be discarded. So that's actually 3.84iGB/RPM (not to be confused with 3.84GiB/RPM, because I won't have any of that "gebibyte" bullshit).
Now, the question remains, does RAM have rotational velocidensity? One could say that it does, because it is using electrons, which have a quantum spin of 1/2, as has already been established. But one would be a fool to say so, because these electrons are FLOWING, not stationary.
Take a look, if you would, at the [url=http://en.wikipedia.org/wiki/File:SRAM_Cell_%286_Transistors%29.svg]circuit diagram for an SRAM cell[/url]. One can see that the primary functionality is obtained by a circle of transistors. It is the rotational rate of electrons through these transistors that determines RAM's rotational velocidensity. Fortunately for us, this is essentially the switching speed of the cell. SRAM has a variety of uses, but the most common one these days, it seems, is as processor cache, in which it is run at the full speed of the processor (for first-level cache) or a neat fraction of it (one-half is common for last-level cache). And so for a common 4.4GHz processor, with 1:1 clocks on CPU and L1 cache, you get an RPM of 264 million. I will leave the remainder of the rotational velocidensity calculations as an exercise for the reader.

Damn son, how do you know all this stuff?!
How would I go about compressing a lossless .avi to around 400mb? I forgot to check my settings before recording and now I have a 56gb file (47 after halving resolution) that is obviously far too big. Upload speed is shocking, not that bothered about quality. I tried a free program but it whacked a nice big logo in the center, so fuck that. I have VDub but I cannot tell if it does anything becasue it won't output a file after trying to compress.

About £270. I was looking for one of those earlier in the year (not any more haha) and second hand they went for about that much. You could probably charge more too if you wanted.
Anyone know where I can get a 10" Tablet with WiFi & GPS (need to use it as a SatNav preferably)
No budget in mind at the minute, just want to see what's available
is there any screen multiplexers (think linux's Screen) for Windows?
Looking for a high end, but good "bang for your buck" set of graphics cards for rendering in Blender.
I'm considering waiting for the GTX 780 ti... but I'm wary of buying new shit because it devalues/becomes obsolete so quickly. Any recommendations for a powerhouse graphics card that won't devalue really quickly?

Just because a new card comes out, it doesn't mean every game and graphics software developer will suddenly make their game require a GPU that's 3 times faster. Your current card will still be kicking fine for several years after new cards are introduced before it shows significant aging in performance. There isn't such thing as computer hardware that won't depreciate in value, you'll just have to get what is good now and don't think too far into the future.

I have 560 Ti's and the rest of my computer hardware is more or less top of the line, the fact that my CPU can get close in rendering performance to thew two GPUs is indicative that the rest of my computer outclasses my graphics cards. I just refrained from buying graphics cards with my new build specifically so I could get more options.

Thats usually indicative of the GPU they are currently benchmarking. So that chart is from the 760 review.
[editline]edit[/editline]
I think he did something wrong when benching that 780, it should be faster than it is in that graph.
Well it looks like the 580 and 680 are the top dogs. The 580 is a bit dated but it's really cheap, far cheaper than the 680.

How risky is refurbished stuff?
Typically not too bad. I've never had issues with it, but if you want the peace of mind, I'd buy new.
I'm a cheap motherfucker so I guess I'll take my chances. Also the 580 is basically sold out and impossible to acquire for SLI, refurb GTX 680 it is :[
Oh well, it'll probably do better in games I guess. Thanks for the advice
You can mix gpu's for 3d rendering.
[QUOTE=alien_guy;42736022]You can mix gpu's for 3d rendering.[/QUOTE]
Didn't know that, though this is a doubling for a gaming computer as well so sli is needed. Might be able to get a cheaper third card. My third PCIe slot is butted up against my power supply though so a third card would need to be a small one, or the cooling components would need to sit on top.
Not sure how that's going to work out
