Uh...
...don't let 'best' trip you up.
Features can be easy or hard to use; yet still are equal in the final product.
Actually holding the product in your hands can answer a lot of your questions; even some you've not thought of before.
And actually USING a product will bring quite a clarity to the picture.
Beware of just reading specs.
Way back (when I still had hair) I designed a chip into a circuit just from the specs alone.
Turns out the specs were true; just NOT at the same TIME!
High speed?
Yup!!
Waveform purity?
Yup
WHAT??!!??
That's supposed to be a SQUARE WAVE?
Thanks for the Ad-vice! Indeed. I am blessed to have built a PC using a ASRock 970 Extreme 4, mobo, a 4.2ghz 4-core AMD 4350 cpu, and 16gb ram, running W/10 pro (which cost 29.99 by way of upgrades from XP) on a SSD HD (plus a sata) but while pretty fast, and able to run with 5 browsers open, with over 400 tabs total, and a dozen documents (no games though, or malware), i thought it would be faster. Cheap (35.00) GPU likely is bottlenecking. But complain, no, thank God, who enabled me to get it thru someone, unasked.
