::From what I've gathered so far, trading software really doesn't need that much power.
Yeah, the only sensible statement, sadly.
::Of course running four monitors is hungry in all hardware sense
Ah - no. Not for some years. Say thank you to all the gamers
Get two LOW END ATI cards of the current 5xxx generation - you can run 6 screens.
Get two low end cards of the last generation, you can run 4.
Most non-stupid normal motherboard supports 2 cards (cross-fire or the nvidia equivalent) these days. Just plug in two cards. Run 6 monitors with current ATI cards. Gets a little more tricky with micro-atx boards - the small ones you dont even have at the macs, as those normally only have one slot for graphics cards. But then, soonish, ATI will publish one card with 2gb ram.... and 6 (!) monitor outlets. I really wait for that one.
ATI current generation REALLY REALLY REALLY suggested - uses lowest amount of power unless you run 3d games
Older generations + Nvidia use a lot more. We talk of 25 watts per card (with 2 mionitors) vs. 80-100, so it makes a financial difference when running extended amounts of times.
::For whatever reason Mac OS X is almost immune to contracting these 'things'.
By no means. Mac OS X is a lot more suspectible than windows to those - modern windows runs anti malware software as part of the normal setup, while Mac OS X does not. And most OS X users dont have anti virus.
The reason you dont get infections on Mac OS X is that it makes no sense to write them. See, for the same time you can target Windows stupid users - which is about 18 times the market share
But deducting from "noone is interested to write malware for the mac yet" that the mac is secure per se is - not exactly smart.
::Firstly, with my Mac I simply plug in a cable, and whether it be my HDTV or monitor, the Mac
::almost instantly configures the desktop and there's no need for any fiddly settings.
Ah. You mean like in - WINDOWS?
The only thing one needs to set up with even decent current monitors (i.e. non "VGA not supporting resultion feedback" - like all did in the last 10 or so years) is - when using multiple monitors - the physical layout, so that the mouse moves nicely out of one into the next.
Now, you say you dont have to set things up on mac like on windows. How does the Mac magically know - when I have three monitors hooked up, how they are organized and in which order? Because this is the ONLY thing you need to set up with windows these days. You know, Windows 95 times are over
::Meaning you do not have to worry about your station crashing right when you need it.
How does Mac OS does that? I mean, seriously.
I had no Windows crash in years that does not go back to some other influence (like serious power fluctutations - crashing some servers and the hardware router on top). Or today - I would really love how Mac OX would handle that. I was installing a new computer for me (for my second appartement) when it stopped responding. Upon restart, the hard disc was not available - damn thing just stopped working
Besides that - sorry, no crash in years.
Plus, given that workstations are unlreliable to start with - you should have a backup unit anyway. Sorry
Discs, power supplies - all can die, also on a mac. Get a backup.
::Having said that, Macs do come at a slight premium (although when you break it down its well
::worth it)
Ah, no. Sorry, It comes with a premium it is not worth these days. Heck, I dont even find a decent hardware arranged mac anymore- they had a great idea with the mac mini, but since then they just gave up. No sensible setups - no servers, no workstations worth buying.
When I compare that with my "premium" home-build pc's (which any shop can put together) - sits on the desk, micro atx, 16gb ram, quad core - small, silent, partially large storage (show me a small mac with 8 hard disc slots, please -I have such a small home server here, same case, same motherboard, just added a raid controller and an 8 port SAS cage into the 2 5" slots for drives).
Going to servers, same thing. My main server is a supermicro rack based system - nice, 2 units high. 2x quad core, 64gb ram. Here is the catch now - 24 hard discs
Lots of power and space - and not existing in the mac workd.
In general:
::If you can, that leaves one PC free for account managing and trade transaction and other for
::charting. The beauty of this is, even if one PC crashes or does something stupid as PCs tend to do,
::you can quickly shift over temporarily.
Could be better - the result of not thinking things through
If you go two machines, get the second one being a LAPTOP, and get a wireless internet connection on top of whatever you use - UMTS / 3G based.
Reason? Not only windows crashes. We get power outages on top, internet provider failures. If you go second machine, make sure you can operate without power and your normal internet connection for extended time (more than the 10 or so minutes a USV gives you).... which means Laptop. And you want to be safe you can still exit positions if your stupid provider decides.... to stop working for the day
