Piriform Speccy
Brought to you by the same people who made Defraggler, CCleaner, and Recuva, Speccy tells you everything you wanted to know about you hardware and quite a bit you didn’t really need to know.
Pros:
Tells you –in great detail – about your OS, CPU, RAM, Motherboard, Graphics, Hard Drives, Optical Drives, and Audio. For instance, it turns out my hard drive’s model is WD1600BEVT-00ZCTO
Cons:
Tells you more than you needed?
Rating: 
9/10

About the ratings:
I copied Wired Magazine’s rating system because I like and I think it works well. Here’s the key:
1 = A complete failure in every way
2 = Barely functional – don’t get it
3 = Serious flaws, proceed with caution
4 = Downsides outweigh upsides
5 = Recommended with reservations
6 = A solid product with some issues
7 = Very good, but not great
8 = Excellent, with room to kvetch
9 = Nearly flawless – get it now
10 = Metaphysical product perfection
Just found this on StumbleUpon, and have to admit, it’s a very nice product. It even told me the temp of my processor. I know that’s nothing new, but it’s impressive it had that sort of functionality for a beta product.
(Psst, when it hits a release version, does it get updated to 10/10?)
Yeah, it’s a pretty impressive beta. I’m not sure if I’ll update it to 10/10 when it hits release — it depends on what (if any) extra features get included.
So, have you checked out the rest of my blog yet? If not, I recommend it. (‘course, I’m a little biased…)
Speccy is a very useful lightweight timple tool… however I have found that for certain graphics cards, speccy reports back as being something too generic like ‘ATI 512m Display’ or something like that.
This is a pain for me, because I mostly use Speccy to find out what graphics card my clients are actually running to be able to download drivers.
Other than that its mostly accurate on everything.
