I have two laptops that I use on a daily basis, almost identical in specs yet they run completely differently. Laptop #1 is an HP EliteBook 8730w, Intel T9600 2.8 ghz with 4gb of DDR2-800 ram. Running Windows 10 Pro, with an SSD. Dedicated nVidia graphics. It runs absolutely flawlessly, and has for years. Laptop #2 is a work unit, HP EliteBook 8440p. Intel Core i5 M520, 4gb ram, running Windows 7 home. No SSD. Onboard graphics with 512 meg dedicated memory, the rest is shared. That poor 8440p can hardly get out of it's own way! I really only use it on Pro Demand to look up service information. Nothing labor intensive. The thing just lags and lags and lags. Would upgrading to a cheap SSD make THAT much difference? I remember my 8730w having a noticeable increase after I installed one, but I don't remember it being that drastic. Maybe my memory is eluding me.
