Re: I helped Dell's figures...
I bought an Inspiron 15 7000 7577
My previous laptop was a Dell (circa 2010, an i 3 540m).
For $680 USD, a 256gb nvme drive, an i5 7300, an nvidia gtx 1060, Thunderbolt 3 port, 8g ddr4 memory. I put an additonal 8gb memory ($60) and a Samsung 850 EVO 500GB SSD drive ($140)
The thing is, in just discrete PARTS, the m2 drive, the cpu, the ddr4 memory and the graphics adapter would cost nearly $680!
I thought it was an excellent deal. This thing is dead quiet unless exercising the GPU. It reboots in 15 seconds ( i kid you not).
With this laptop ( and esp with the Thunderbolt 3 port), I am declaring that I will never purchase or upgrade another desktop computer. Ever. A laptop can now do it all.
