This has gotten pretty funny! Thanks everyone for the input.
This is just a basic gmail, tons of youtube for the kids, some word and excel docs machine.
I have either 12 or 16GB ram, Ram was cheap and I rolled some over from my HTPC in to this.
My wife loves to have a hundred tabs open in Chrome. I think that will probably be the biggest hog.
I may not even up grade. I think most of the issues are from an Intel AC-7260 wifi card. I found a lot of people having issues on Intel's forums.
But I do want to move to a smaller case....
I have pushed Chrome tabs into the 100+ range easily myself. So often that I know that Gmail is a pig of a website. So is Yahoo and most other email providers. Facebook is also script heavy. When Chome is freshly opened, an i3 or G4560 will go through the websites with the greatest of ease. But throw in a whole bunch of tabs, and annoying background processes like Windows svchost pegging a core to 100 percent again, and then one appreciates having two extra real cores.
I have used Sandy Bridge Celerons and i7-3770s and Ks on the same system(I sold off the i7s for coin). When Chrome is "empty", there is a difference in lag between the i7 and Celeron, which I suspect is due to clockspeed. An i3 would be indistinguishable from an i7 when the system is barely loaded. But when the session ballons from whatever web browsing adventures the user comes a across, the real quad core will start showing itself.
A hundred tabs in Chrome will gobble up most of the RAM present in a 16 GB RAM system and start hitting the pagefile. An SSD will mitigate the thrashing if budgets limits the buyer from getting more RAM, but those who can afford it would be well advised to get both the SSD and more RAM.
I have too much time on my hands and close my Chrome tabs one-by-one, with a screenshot before killing the page. Needless to say, the process lets me see how the memory and CPU usage goes down as tabs get closed.
Ivy Bridge or Haswell i5 prebuilts with RAM expandable to 32GBs should be considered a purchase option.
Doing something like having a ton of Redfin tabs open will make anyone realize that some websites are truly resource boat anchors.
Your wife might want to try out Vivaldi as a Chrome alternative.
Oh, and I also disabled Chrome "auto-closing" of tabs cheat they employ to reduce RAM usage. I do not like my tabs being reset.
