I have an Athlon xp 2400+ which I still use and happily runs Eve, but it's no more than a backup machine now to be honest.
Sounds like someone built a library without legacy CPU support, I'd be curious as to which libraries are causing the problem. Or maybe I should just try running SiSi on my old machine.

Someone suggested that this was in the physics library, and I can see how that could be a problem with no easy resolution. I mean generally the way code works is that you develop the core functionality using plain old C which will work on every CPU, then at a later date you use things like SSE to improve performance where the features are available, there's no reason to remove the reference code.
One of the things that SSE2 lets you accelerate is floating point operations, but the floating point operations don't behave exactly like those in the x87 floating point processor, so in some cases the results can be slightly different due to the way temporary results are stored.
Now in Eve, everyone is running a copy of the physics simulation, and to avoid desync everyone needs to keep getting the same results. So, hypothetically if some users were running an x87 implementation and others were running and SSE2 optimized version we could see desyncs happening. Since the performance gain would be quite appreciable I can see that the anti-lag team might decide to start the servers running SSE2 physics and only later realise the effect on outside clients.
of course this is entirely guesswork.....

In that case, the removal of non-SSE2 CPUs from support will help the dev team migrate all physics simulation to the SSE2 compiled code base. Both the client and the server code will have to undergo an overhaul though.
I'm pretty sure the overhaul is -M_ENABLE_SSE2_PHYSICS when you compile the physics library.....

It just seems to suck for everyone involved, I hope Eve customer support will be able to offer refunds to affected individuals, since 2 days is not enough time to get a new system, especially when one of those days is a weekend, and the next is a holiday in the US. A replacement graphics card at short notice is easy, but a CPU need Motherboard, memory and most likely an OS reinstall, easier to just buy a new system.
Having done some poking around I'm thinking that it's not likely to be destiny, it's more likely to be related to the physics engine used for hair and clothes in the new character generator. (Although they may have updated destiny to make use of this?).
Which is unfortunate because as recently as July there was a lot of technical bad press surrounding PhysX for being overly reliant on x87 and not using the accelerated SSE2 instructions. The conspiracy minded were arguing this was a deliberate ploy by Nvidia to sell more graphics cards (which would handle some of the physics).
Anyway... I can live without physical simulations of hair.

Honestly, if someone is still playing EVE on a 7+ year old PC...
That's like complaining that Duke3D doesn't run on your ZX Spectrum.
Forgive my inner geek but, it's more like complaining that a ZX spectrum released in 1982 couldn't play the latest and greatest 3d games from the late 80 - games like Carrier Command, Starglider 2.
Oh wait both of those were in fact ported to the Spectrum.
How about Doom - oh no that was ported to the spectrum as well....
CCP in no way intended for these CPU's to be deprecated, but I'd like them to be open and either and give us a clue as to whether a client fix will be possible, if we can hold on a couple of weeks or, if this is an issue which will not be fixable.

It's not about obsession over having bleeding-edge hardware, it's about having hardware that's less than 8 years old.
Processors without SSE2 support were still being made in mainstream systems until 2005, so it's not 8 years.
2005 was also the year that the Xbox360 launched, are you suggesting that it's also obsolete?

There are no pin compatible processors which will support SSE2, sorry, you're basically looking for a new motherboard, memory, processor and OS install.
(unless you're some ninja elite linux kernel hacker who wants to ressurrect the SSE2 emulation feature in the linux Kernel)

The Commissioned Officers Edition is still available in stores too, and being advertised with specs that now don't work: CCP - you probably need to either fix the SSE2 requirements soon or contact all the retailers and advise them on the spec changes.

What's upset people most is the fact that this was sprung on us with no warning.
Plus, yesterday in town I found computers on display and being sold by major national
vendors that only support the basic SSE instruction set, not SSE2, and I had to ask specific questions to find that out.
Where is this? Frankly I wouldn't trust the average sales drone to be able to answer this question correctly, and most modern processors do in fact support SSE2. The AMD Geode processor which is used in some Netbooks is only example I can think of and those netbooks also lack proper graphics cards.
