I am having a cold, yesterday evening I had rather high fever and was unable to do much more than watch tv and sleep.
Anyway, today I am feeling a bit better and am able to use the computer, at least.
So I got back to thinking about selecting parts for my next computer. I got a laptop recently, but I want to play some recent games such as crysis. Neither my laptop with integrated Intel graphics nor my soon three years old desktop with an amd64 3000+ and a nvidia 6600gt are really up for the task.
I tried the crysis demo on the desktop a while ago, and I was able to play through it on low settings, but that is not really playing, now is it?
Anyway, back to the new computer. This will be a gaming machine, so I think I will buy Vista with it. Yes, I know Vista is a hog. Xp is more easy on the resources, and games such as crysis can still be tweaked to run on it with maximum settings.
Still, Xp is on its way out, and soon new games will have reduced support for it and its directx 9.
So Vista it will be, 64 bits to support enough memory for eventual future upgrades. Perhaps in a dual-boot with Linux but here is the other decision: I will not spend any effort at all to ensure Linux compatibility. That would make too many factors to consider and I want to focus on price/performance and quality. Selecting a linux compatible printer is enough research, I have enough problems choosing hardware without thinking about linux. Still, if I choose between two components equal in everything else linux support could be the tipping point.
Not that I am too worried, most part are compatible nowadays. Plus when I selected the current desktop I had not yet discovered Linux, still every part works perfectly with it.
So, on to the hardware. This is where I am at right now:
I have pretty much decided on the case and PSU: An Antec Performance P182 and a Seasonic S12 Energy+ 550W.
My main deciding factors were in order:
Quality. The antec case has had many positive reviews, plus antec is one of the best when it comes to enclosures.
Seasonic is one of the(if not the) best when it comes to power supplies.
Power efficiency. Not much beats the s12 energy+.
Noise level. Both the s12 energy+ and the P182 are in the top in the tests I have read.
So, that was the easy part I guess.
Now on to the more difficult stuff. This is where I have not really decided yet.
The platform, AMD vs Intel?
Intel is ahead, even of the new amd spider series, from what I have read. So that should be a no-brainer: Intel.
Motherboard: I want a good quality motherboard that has the features I need, but not an overpriced peice of junk that has a gazillion features I will never use such as built-in wireless for example. If I would ever need that in my desktop, I would rather get a separate wireless card. Less pieces that can fail in the same unit.
Oh, and it needs to have a lot of heatpipes since they look cool. 
I have had good experiences using Asus motherboards in the past(other than their terribly slow servers when downloading drivers, have they fixed that yet?) so it will probably be asus.
My current candidate is an Asus P5K.
Cpu: dual-core vs quad core? That is tricky. Currently, dual-cores give more bang for the bucks, while quad-cores have the potential to beat them when new games and applications take full advantage off all cores.
I am currently leaning towards getting a dual-core now, and possibly upgrading when quad-cores are better supported and have dropped a bit in price. A Core 2 Duo E6750 is chosen for now.
Memory: I have not researched a lot yet. Vista takes it fair share of resources, so perhaps Corsair TWIN2X 6400 DDR2, 4096MB.
Or possibly stick with 2 gig for now and upgrade later if needed?
Video card: Oh, this is difficult. I would say a nvidia 8800 gt with at least 512 MB memory.
Asus? XFX? Gainward? EVGA? Someone else? Efficient/silent cooling would be a plus.
Other:
Seagate Barracuda 7200.10 500GB
NEC sata DVD burner, no more IDE cables for me.
And possibly an external usb floppy drive, if the motherboard has a retarded bios update procedure.
Monitor, I think I can use my current 1280×1024 LG flatron for a while longer. That is, unless I sell my current desktop instead of keeping it around collecting dust. Then I could sell the monitor along with it and buy a new one… Why would I keep the old desktop anyway? I can still not use more than two at a time(the desktop and laptop).
