I will upgrade on one [not-so-important] machine to see what all the fuss is about, but I will maintain my primary machines with Win 8.1 until I'm satisfied Win 10 is safe to install/run. If it is then I'll take it from there, though I would likely want to keep one rig running Win 8.1. Hopefully Stardock has all the customisation tools ready to dress Win 10 properly... cos its current wardrobe [GUI] is butt ugly and in serious need of tossing out. But then, MS never could get a GUI right.
You readin minds these days, mate?
Actually, I will probably "upgrade" (?) one of my 8.1 rigs that has at least 10 GB ram, a 6 core CPU, an SSD, and a high mid range gfx card (in it's day), just to compare to 8.1 with the same hardware. Keep the other 3 with same hardware as 8.1, at least until I can get a feel for 10.
I have 4 rigs with the exact same hardware other than mobo. So I should get a good comparison. 4 of my rigs have 6 core AMD CPUs ( 2x 1045T, 1 x 1055T, and 1 x 1075T.), 120 GB SSDs, and comparable gfx cards, ( 2 X GTS 450, and 1 X GTX 650). I have a core i7 rig with a GTX 560 twin but it's on a locked down mobo.
Which should I put 10 on? I'm thinking one of the 6 core AMDs, so I can compare with 8.1 on same hardware. What do you think, Mark?
At the moment, I'm running 10 with 4 GB ram, a HDD, a lower end GFX card, and a core 2 duo.
