I've never had any major problems with 7...in fact to date it's my favorite Windows OS. But after recently buying an Asus K55N laptop for school that came pre-loaded with Windows 8 I finally decided to sit down for more than 10 minutes and give it a shot. I actually don't think it's all that bad..I love a few features like the task manager and all that it monitors and how snappy everything is on the laptop. Not having a start button is weird and I was thinking about Start 8 for $5 or maybe a free one...but I've challenged myself to just using it more as-is.
So far, I gotta say I like it! All the negative I have read and heard from almost everyone had me discouraged and what few minutes I had tried I hated...mostly because the Start button went from a useful tool since Win 95 to a challenge to live without on 8. But the more I mess with 8 the more I find I can access many different parts of windows and utilities in fewer clicks.
So here I sit...do I upgrade from my Win 7 Pro x64 SP1 setup? Ask me a year ago and well I might not even accept that as a logical question, and today I am seriously considering it. And with 8.1 looming I am interested, though I'll admit I haven't researched too far I feel I'm ready to give it a full chance on my gaming rig after impressing me with what it can eek out of my K55N, which while thus far it's a great little cheap laptop...it's doing better than expected in all aspects I've used it for thus far!
End of this long post....I'm thinking about installing Windows 8 on my gaming rig after being impressed with it on my laptop. And with my SSD and UEFI bios on my Z87 I should have some very good startup times. Though 7 is pretty quick when I trim the startup fat of Origin, Java, Adobe, Google, etc...
