As I continue my tests of Installing Windows 8 and post the results here, I came across an older one today. The Compaq Presario V2000 V2606CU. For this test I am using Windows 8 Enterprise 32-bit. I am doing a clean install, keeping nothing, but you could do a migration keeping your files, but not your settings or installed programs.
I booted to the DVD and installed Windows 8. Once setup was finished there were a few drivers missing. Just run Windows update (make sure to keep running it till you get all updates) and it installed the missing drivers. One thing to note if you check the graphic card it comes up as Microsoft Basic Display Adapter. I have not found any drivers for the ATI Radeon Xpress 200M that this machine has that will work in Windows 8. This makes it so you can not get any higher than 1024 X 768 resolution but that is all you need for the metro apps. You may notice that the video performance on this machine is lacking though.
As far as performance, Windows 8 runs alright on this machine, I can tell it needs more ram to run smother but it runs. Like I said earlier not having the graphic card supported also takes a performance hit on this machine but if all you are doing is browsing the web, checking email, and writing Word documents (or blog articles) then it works well enough. This machine does not support Hyper-V 3.0. I ran PassMark Performance Test and it got a 138 and below is the Windows Experience Index.
If you just want to check out Windows 8 and have one of these Compaq Presario V2000’s around I would say go for it but if you are still using this machine for day-to-day computing you might want to stay with Windows XP or look at Vista or 7 as there is a better chance they may support the Graphic Card. Also I would look into upgrading the ram in this machine for smother operations.
