Its strange reading your comments about 'Why Vista'.
here in the OCUK forum we are always trying to get the absolute most from our components by overclocking them. many, like me, enjoy the thrill of getting the latest equipment... often getting the lesser, cheaper, version and making it run as fast, or faster, than the more expensive option. Every time you stress your system in this way there is pottential for some unreliability. Most of us that overclock suffer from the odd blue screen or system lockup from time to time. So why is Vista different? If you get the odd error or the odd bit slows down unxepectedly, is that not a challenge, like finding the optimum overclock?
I thought that most people here were enjoying the forum because they rise to a challenge and saving money through overclcoking... personally i see Vista in the same way... exciting
I have now been using Vista as my main OS for work and play (i work for myself as a web developer, database engineer and business consultant). I have XP as a dual boot but use it less and less these days. I also enjoy LAN parties and have used Vista as my only game OS at a couple of these.
I started with RC2 5700 and now run the MSDN released version.
Personally, I have found Vista very, very reliable.
Personal Pros...
1. Love Aero, it looks nice and is actually usefukl to see thumbnails of open windows in the taskbar.
2. The search facility is excellent and i use it all the time.
3. Built in Media Centre (in Ultimate) is excellent (i use this because i have an HTPC case with remote control)
4. There is more protection. Many files are harder to change which although frustrating from time to time is a very good thing.
5. USB devices that constantly failed on XP work flawlessly in Vista (for me). I use an o2 PDA phone, which XP hates. The case IR controller again works perfecrtly in Vista, but XP hates. - these are just a couple of examples.
6. The gadets are very useful when working. I use various linked gadgets to outlook.
7. Personally I have not had any issues with getting games to work. I use the following... UT2003, UT2004, Q3, Q4, COD2, Oblivion, F.E.A.R., Far Cry, Flight Simulator X, Toca Race driver 2, NFS Most Wanted, NFS Carbon, GTR2, Half Life, Serious Sam 2, Battlefield 1942.
Cons..
1. 3d mark scores (and by deduction game speed) are a littkle slower in a like for like case. for example 3d2006 looses about 200 points.
2. Uses lots of Hard Drive space... I would say double XP
These are just a quick run through my thoughts. My games / LAN experience was while using a single Connect 3D 1950XTX with beta Vista Drivers.
