Minimum computer specs for general users?

I work on computers and often come across some real duds of a computer. For example, I had a woman upset with me the other day for installing Kaspersky Antivirus on her system because the computer doesn't have enough guts to run this in the background and thus I slowed her computer down. I don't remember the exact CPU but it was some low-end AMD dual core like what you would get in a system from Wal-Mart. This wasn't a Wal-Mart unit but might as well have been.... It had 4GB of RAM which I consider acceptable for basic office usage as this system was being used for.
I generally think that a Core i3 (or comparable AMD) with 4GB of RAM are the basic minimum specs for buying a new computer. People say they only need a computer for documents and e-mail use so don't want to spend a ton of money. I have found that by going cheap, they end up stabbing themselves in the foot. The performance and reliability of some of the cheaper units is just quite poor if you ask me. In addition, these people end up being the ones who complain about the cost of repair and my billing. They just want everything cheap.
I also use the Passmark CPU benchmarks that are posted online as a general reference. I have noted that my minimum suggested CPUs tend to have a score of around 2000, give or take a few points. Some of the really gutless processors have scores well under 1000. These are usually AMD A or E series and often come from Wal-Mart. I have also noticed that in the low end, I would pick an Intel over an AMD any day. If someone told me I had to pick between two of the cheapest computers at Wal-Mart and one was AMD based and the other Intel, I would pick the Intel without question. Of course I wouldn't suggest this type of computer to anyone, but my experience is that the low-end Intels perform a lot better than the same-price AMD unit.
I generally prefer Intels as you know but figure any AMD scoring around 2000 on the Passmark score should be just fine for daily use.
I find it interesting that a 9-10 year old Core 2 Duo system can still perform many basic tasks with power to spare while some new cheapo unit falls on its face right out of the box. Again, I check Passmark and these score around 2000. Some Pentium's also score pretty comparable to the slower Core i3s so that isn't a bad option.
One another note, I almost thing an SSD should be standard equipment these days. For not a lot of money a 128GB SSD can't be beat for bringing a computer to life.
So, my basic suggestions would be a Core i3 with 4GB of RAM and a SSD. Of course my main computer is just a little better than that. It has an i7 scoring about 8000 on Passmark, 6TB of SSD storage (2TB and 4TB), and 8GB of RAM.
Anyone else have anything else to add to this?

Any help appreciated.

I didn't find the right solution from the Internet.
