Tried Vista Ultimate (32b). Too much of a resource hog. Although I have not tried it with my new rig...aaaand probably won't.
Well here in lies the problem. Its based upon the memory usage. Vista (32bit) was designed around a base computing sector (The Home User), as with traditional 32 bit operating systems, you are starting to hit a wall, where your memory is truly becoming the key to performance.
Windows Vista (32Bit) Does a ton of "pre-fetching" of memory, and backloads the Operating system with a Huge Memory Buffer, Now when you go to run a game (which increasingly requires more and more memory), it hit that wall, basically where the Operating system &/or Game thinks the system has "run out of memory" and begins paging to disk. This usually occurs with machines configured with (1or2) gb of ram.
Now is you want to put a band-aid over that, you can get a "Ready Boost" enabled high speed USB Flash drive, and then the operating system will conduct its "pre-fetching" operations to that high speed flash, and free up more RAM for your extended applications.
But the silent killer at hand for an increasingly larger amount of gamers is the (32Bit) operating system itself.
Without writing an entire diary on the insufficiencies of a 32bit operating system, ill keep this short and sweet.
Applications & The Operating system operate usually within the first 2048mb of the system.
Although the performance benefits of 64-bit are somewhat dubious on the desktop, a 64-bit OS absolutely essential if you run applications that need to use more than 2 GB of memory. It's getting more common with games now a days.
If anyone want to discuss issues related to and/or see the performance benefits of a 64 bit OS, pm me or stop by at the next lan.
Cliff Notes - If you want to run vista, skip the 32bit OS, buy 4gb of Ram and (if your hardware supports it) run Windows Vista x64.
Or stick with Windows XP, until you have the need to move up to an Upgraded OS.
Just remember this, When we made the transition from Windows 98/Millenium to a Windows 2000 Code base built on the NTFS Platform, we hit a huge wall of resistance from users & corporations, it took some adoption time to get used to the in's and out's of the operating system. Hell even hardware manufacturers were not writing drivers for their hardware without some prodding, and that took a while.
Vista will get there, SP1 holds alot of improvements, but still wont deal with "older" hardware. Its a Next Generation OS, looking ahead to further pc improvements, the standardized use of Multi-Core Processors, etc.
