Since you guys are already bragging about your computers let me do the same about mines

WARNING long post ahead

1. the oldest wokring computer I have is more than 20 years old PC with AMD K5 100 MHz CPU which I oveclocked to 166 Mhz (simply forcing it to higher FSB). Luckily this CPU has error self correction which is working overtime in my configuration. Anywhay based on WinTune 3 (old WIndows 95 based benchmarking utility) the CPU actual usable performance is comparable to 143 MHz pentium CPU.
Computer has 32 MB of DDR RAM, 8 GB hard drive and TEACK 4X CD rewriter and S3 Virage graphic card with 4 MB of video memory..
I have both DOS 6.22 and Windows 98 SE installed on this computer.
This computer is powerfull enough so I was even able to play games which specify 200 Mhz processor as minimum requirements.

2. Second computer of mine is a bit younger but still over 10 years old. I have built this one myslef.
CPU: AMD Athlon XP 1800+ with 1,5 GHz which I had overclocked to 1,8 GHz for amore than five years but had to revert back to stock settings in the end due to ocasional sudden system resets. I'm not sure wheter this is due to CPU or Motherboard since I have no suitable hardware to test this (equal CPU or Motheboard).
RAM: 2 GB of DDR2 with 400 MHz frequency (max that my motherboard supports).
Graphic card: AGP 8 based Saphire ATI Radeon 9600 PRO with 256 MB of video memory.
HDD: Western Digital Caviar 200 GB 7200 RPM. Like it is common on my computer Hard Drive is almost completly full.
Optical drive: TEAC CD/RW 52x and TEAC DVD/RW (not sure for DVD/RW speed thou)
OS: WinXR Pro and dozens of other more or less usefull programs

3. My first laptop Acer aspire 3025 WLMi
CPU: AMD Sampron 3300+
Memory: 512 MB of DDR2 RAM
Graphical card: ATI Mobility Radeon X700 PCI Express with 128 MB of video memory
Hard drive: Western Digital 160GB (replaced the old Fujitsu siemens 80 GB)
Screen: 15,4 4:3 screen ratio
Optical unit: DVD/RW (I don't rembember the manufacturer name).
OS: WIndows XP Personal Edition OEM.

This laptop seved me well for many years. But now it is not quite usefull any more since the heatsing fro the GPU buckled due to heat and no longer provides suficient cooling to GPU which causes system to reduce both my GPU and CPU speed to prevent overheating. This in turn makes computer work realy slow. So I mostly use it for storing backup copies of some of my files.
I tried to fix this by disasembling whole laptop but I couldn't unscrew those tiny GPU heatsink screws as they literaly melted into casings plastic. That is no wonder since average CPU temperature when playing demmanding games was 78 degrees celsius. When playing S.T.A.L.K.E.R it even reached 85 degrees celsius. That was just before my HDD shuted down due to overheating (I had to fecr windows into using bigger page file so that STALKER had enough memory available. But this caused to much pof work for my HDD. Luckily this was after I have replaced original Fujitsu Siemens HDD as that one doesn't have shutdown on everheating capability.
This laptop was my first computer which I heavily used for programming (learning of it). Naturally for this I have Delphi 7 installed on it.

4. My newest and best of them all is Acer Aspire 6530G laptop which I using right now
CPU: AMD Turion X Dual Core Mobility with 2 GHz
RAM: 4 GB of DD3 RAM 666 MHz
Graphic card: AMD Mobility Radeon 3650 with 512 MB of video memory and Shader 3 support.
HDD: Western Digital 320 GB 5400 RPM SATA3 and Western Digital 500 GB 5400 RPM SATA3. Yes I have laptop computer with ability to have two hard drives at once. I was first thinking of upgrading my laptop with a SSD drive but once my old HDD started acting wierd ocasionally I decided to buy 500 GB WD instead as I though old HDD will just die. It is still working with ocasional sudden shutdowns which then require system restart for it to wake up.

This computer is now 4 years old (model year 200. But despite that I can still play most newest games with it. The only ones that are giving me troubles are the ones who require athleast Levl 4 Shader support. And when I think of that I payed just about 600$ for it well all I could say that it was probably the best bargin I could get at that time.
The laptop only has two flaws I found so far
- while the laptop does have full keyboard including the numerical part both Enter keys acts only as numberpad enter so this is sometimes giving me some troubles with games which specifically require to pres VK_RETURN at certain times
- the laptop is equipped with tuba speaker which greatly improves the sound expirience but unfortunately sound card has stereo subwofer output and both left and right signals are physically conected to one Tuba speaker. This can sometimes cause some wierd sound distortions comming out of Tuba speaker when thwo threads for processing Left and Right audio channel lose their synchonization. This is especially big problem on Windows Vista and nwer becouse Windows is the one that can adjust processing priority even to hardware drivers. When I installed WinXP as dual bot I never expirienced such problems with audio becouse on WinXP the drivers always have priority over other programs.

Besides these four computers I have lots of spare components mostly for realy old computers

What will I want for my next machine:
-athleast 8 core CPU with athleast 3 GHz per core. Preferably true 8 core CPU and not just 4 core CPU with hyper-threading support. Mybe even a dual CPU system
-athleast 16 GB of RAM so I can make use of RAM drive functionality to speed up some things. Having 32 GB of ram would be even better
-having SSD for the OS and 1TB for data which still might not be enough for me
-system with two graphical cards or athleast one with 2 GPU's
-dual monitor system (would come in handy sometimes. Right now I sometimes use combination of two computers (my laptop and my PC)

If I forget about dual CPU and dual graphics card setup I could probably build such system for about 1500$ but that is too much for my current financial situation (two full paychecks).
