Windows XP FTW. There are NO games that currently take full advantage of DX10--even Crysis can be modded to get high detail in XP.
Save yourself a lot of money--a lot of bloat--and a lot of disappointment--get XP now and wait for Windows "7."
Yes, wait until 2011..... enjoy waiting, you dont like vista, sorry to hear it, theydidnt ask about XP, they asked about Vista, what if they want to use more then 4G of ram and actually want decent driver support... (there goes XP32 and Xp 64bit)
Well, it has been seen that there can be up to a 30% performance hit from XP to Vista with the same hardware...
So I think that this would be fact...
Plus you need all these other things enabled to get it to run faster.. Funny stuff like: Prefetch and Ready boost..
IMO, These things were after thoughts.
If it were such a great OS, there would not be a need for these speed boosters...
You guys should look into Windows 2008 server, all the bloatware is removed, and you can turn the things on that you want. It even comes as a CMD prompt version as well... and get this, can run on 1 gig of RAM without any issues....
Maybe a %30 hit on year old + reviews, more recent ones show a far ,less, FAR FAR less hit on performance, and the general improvement of memory management, superfetch and such makes vista react much faster then XP, for most, and myself, at least.
And those other things are already enabled by default...
it is a good OS, they are in the OS, how does MS including something in the OS, not make it good? that makes no sense, they have it in the OS - they just decided that you can turn it off it you like..... how is having a choice a bad thing.
Most people dont have $500 plus for a server operating system (i think just over $400 for the web edition, about $600 for standard), and many things, dont run on server 200*, such as many home anti-viruses, various games need patching or hacks to get to work as well.
Vista can run on 1g of ram with out issues as well. you can turn off all the fancy smanchy goodies making it basically XP with a newer kernal and better networking.
