I need help in finding legitimate information to base the layout of my testing matrix for web testing in my lab.
Ideally, we only want to keep 26 machines in our lab. I need to know where I can find what Processor, memory, and video card specs a typical user has at home and work. I need from the lowest specifications, to the highest. These need to be both PC's and Mac's. Are there any government sites that have surveys of such? We are in need of re-circulating the matrix we have now.
Thanks in advance.
Re: Testing Matrix
Take a look at some back issues of CIO magazine. Occasionally the topic of lengths of leases for PCs come up, as well as the subject of average cost for the base PC. You should be able to use this information to come up with a rolling window of average PC's. Of course, the one's at the late end of the window would tend to be the weakest.
I wish I could provide a specific hardware spec, but this should give you a place to begin to set what would be a reasonable standard for a corporate environment.

Re: Testing Matrix
Assuming that system software (O/S, Browser, Plug-in) is also going to be a variable in your testing matrix? I would suggest you also consider using some form of "ghosting" software tool to allow you to easily load each system software configuration onto any of your hardware configurations.
Examples of "ghosting" tools include: AlohaBob’s PC Relocator (alohabob.com), Altiris’ RapiDeploy (altiris.com), Higher Ground Software’s Drive2Drive (highergroundsoftware.com), IT Infusion’s ImageCast (it-infusion.com), Altiris’ LabExpert (altiris.com), Norton’s Ghost (symantec.com), and StorageSoft’s (storagesoft.com) ImageCast
If you do decide to use a "ghosting" tool, I'd suggest to try keep as many of your PC's (or Mac's) from the same hardware family and generation (e.g. All machines are from the Compaq Presario 5000T series) as different PC vendors tend to use differeent drivers (video, network etc) for their machines, which may make it much harder to resuse on PC#23, a ghost image originally recored on PC #1.
Hope this helps?
