Wich one of 4?
My daily driver was 6 years old with upgraded ,RAM (more of it ) , Better GPU to replace the on board video , AMD 6 core CPU ,upgraded Storage drives including an OCZ Vector 180 SSD , and a discrete sound card .
Eventually after all that it was running windows 10 x64 fine by then and then the main board failed so I ordered this 2016 HP Pavilion Haswell Core i5 tower with 8 GB ram the same day and I got it 4 days later .
I put the the sound card & SSD in here dual booting clean windows 10 alongside the OEM 1 TB metal hdd with a clean windows 10 AU install on it and the OEM bloatware OS nowhere on it .
I found an NOS exact replacement OEM main board cheap on E bay for the old PC , fixed it wiped the drive DOD style re installed windows 10 and sold it for half of the cost of this new one .
The Core i7 HP Elitebook is maybe 3 yrs old , the game box is a late 2011 recently upgraded SB Core i7 box that still plays well with its 2015 nVidia gaming GPU and 650w PSU and there is a Dell Optiplex 780 Core Duo $80.00 e bay score on windows 10 that gets casual use in another room occasionally ,No plans to replace anything here at this time and this Haswel Core i5 daily driver is fine for what I do with it .
