For me:
I have got and Toshiba Satellite laptop given for free by my School, for educational purposes, after 2 OS reinstalls, it has now a unfunctional WiFi card under Windows. (Yet it works under Ubuntu. WTF kamarad???)
It has : Pentium Dual-Core 1,95 GHz
Intel HD Graphics onboard chip (Sucks ass, but STALKER : SOC is playable with minimum graphics)
SomeLousyCrappyTekSoundClusterfuckChip Onboard
111 GB of storage.
Wyndoze 7 32 Bits OS
2 GB of RAM
I have also an jiggly-rugged gaming-oriented pc who costed me 0$ as I have recovered parts here and here.
-Pentium 4 - 2,80 GHz (Will be upgraded to 3 GHz +)
-Radeon X1550 256mb of DDR2 vram. (Provides enough power for the games I intend to play.)
-Seagate Barracuda 80GB dedicated drive for OS / Seagate SATA Barracuda 120 GB and Maxtor IDE Diamond MAX Plus 9 120 GB for storage (Gonna try RAID)
-2,50 GB of old-school RAM
-Windows XP Pro OS 32 bits
-Hiper HPU-3S350 Power Supply Unit
It took me forever to set this up, I had to install XP to the drive using Another PC as the BIOS didn't recognized the OS DVD, plus I had to tear/massacre the original Dell computer case where comes from the Motherboard. (The case was office-oriented, it ABSOLUTELY wasn't designed for being modded, i even had to cut a entire piece of metal and a aeration grate)
Overall, using my old Athlon XP with 1,5 GHz, 1,5 Gb of RAM, and the Radeon Card, STALKER : SOC was well-playable with standart settings, So I exept only superior performance. I still have to install drivers and pimp my GPU with Afterburner and Kombustor.
The list of gameZ i am going to play:
-Silverfall
-STALKER:Clear Sky
-Call Of Duty 2 (Not to confuse with the awesome blockbuster Call Of DOOty)
-Rainbow Six : Lockdown
-Enemy Territory : RTCW
-Gothic 3
-Alien Arena 2006 UE
-Unreal Tournament 2003
And i can still play using GL mode (although i should not abuse on DLights or things like voxels - wwdoomnukem is almost unplayable here at certain areas because of that). This ain't my main machine, but is the one i carry to my job, and probably is the computer that i used most for ZDoom stuff.
