Dell XPS Core i7, GTX 1660 SUPER 6GB Graphics, 512GB SSD+1TB HDD Desktop For $849.99 After $500 Off Code, As Low As $664.99 With Business Platinum Card!

Lots of tabs uses up RAM, not the CPU or GPU. 4k video is mildly graphically intensive (for modern systems, for older ones it is heavy) but any modern integrated GPU will manage just fine without help.
Unless you need the dedicated GPU the system won’t use it at all. All modern computers automatically optimize efficiency and won’t use more power then needed. Powerful GPUs are power hungry so it won’t even turn on until needed.
If I remember correctly Dan, you’ve written that you’re happy with your XPS13, which only has dedicated graphics.

Edit* only has integrated graphics.

I would also like to point out that this could be a great purchase if you’re willing to remove the 1660 and sell it on eBay. They’re currently worth roughly $400-500 because of the chip shortage. And you’d still be left with a great office PC.

You seem to know what you are talking about and we want to get new desktops for our office. We need one that our secretary remotely logs into and can run an internet filter on without slowing down. I was told it should be at least i7 for that. Any thoughts? Any recomendations?

Unless the filtering is happening on the PC (quite a rare set up, a typical filter is simply directing your internet through their server where it is filtered there) there isn’t much you can do to improve the speed. Obviously you need the best internet connection you can get both for the office and for wherever the secretary is logging in from. Ideally the connection would be wired (meaning an Ethernet cable instead of wifi). But beyond that the factors affecting speed of the filter are mostly out of your control (besides for switching filters). CPU barely has anything to do with it. However if your experiencing slowdowns it’s probably not the filter or the CPU. I would first make sure you have a reliable connection on both ends. Then make sure your storage is a SSD. After that make sure you have enough RAM (8gb is enough for basics, but if you tend to have lots of programs and/or tabs in the browser open at the same time then consider 16 or even 32gb).
For ordinary office work an i5 or equivalent AMD chip should be more then enough.

I disagree. As someone in the tech field I deal with users who insist on having thier computers filtered. The filtered computers run slower rhan others even when people are sitting next to each other.

Where do you disagree? I wrote that the factors are out of your control, not that the computers won’t be slower. Unless your talking about on device filtering there’s nothing on the computer to slow it down. Any delays will be due to latency or the filtering companies computers being slow.
All this is only relevant to the web loading slower. If the whole computer has slowed down then there’s a different issue.

This is a great PC for anyone who edits videos or very large photos. It will be decent at AAA gaming but not amazing for the latest titles.

Mogul you know your stuff.
I will allow myself to ask you a similar question:
Looking to buy a laptop that will be used to work with many PDF files open simultaneously, with excel and word running all the time, with Otzar Hachochma open all the time.
i am ready to spend the money – since i need the speed.
I will look for a SSD drive – of course

Now to the 4 Questions:
1- What type of chip would you recommend? (i7/i9, which generation?)
2- How much RAM? (any specific type of RAM)
3- What type of graphic card?
4- Anything that i missed?
Thanks in advance

1- an i5 is enough. Ryzen 3000 series and up is also just fine. In a laptop the main limitation is cooling so the benefit of an i7 is marginal. 10th or 11th gen Intel are very similar with the main difference being updated graphics so go for 11th if you could, but 10th is totally fine. ( AMD ryzen chips are very competitive and often better then Intel these days so I would recommend those as well).
2- if you will have lots of things open at the same time go for 16gb ram, if you are a real power user maybe even 32gb. This is much more important then the CPU.
3- based on your description of your usage you don’t need a graphics card.
4- a good display, keyboard, and trackpad is not something to overlook in favor of internal specs.

Nearly every modern laptop will be totally fine for you, but I would recommend considering moving to Mac if you could. The new m1 MacBook air is great. (obviously not everyone can switch and the MacBook air is only 13 inches so if you want something bigger then stick with Windows
