I game more than anything on my computers and IMHO WIN98SE is still the only OS that is aceptable for this. I have tried them all but ME, I run pretty hot machines and XP seems sluggish compared to 98SE. Maybe I dont have it setup right, I dont know. But it should be somewhat ready to go without a bunch of tweaking. It just doesnt seem as SNAPPY as 98SE, I am using a 8KHA+ mobo, XP1800 proc, GF 3 vid. card. XP is more gamer friendly than W2K but 98 is still my OS of choice. As far as stability go's I dont have much complaints with 98SE once it is setup properly, Maybe the fact that I shutdown at nightand reboot everyday has something to do with it, but I am not running a server or anything. I have grown to like some of the features of XP pro and the fact that is is very user friendly, but I am not gonna give up 98SE and totally convert until it matures some or something better comes down the pike.
It kinda pisses me off though that ATI doesnt support 98SE with there AIW 8500, so I had to go with a V8200 VIVO card. So far this is the only draw back I have found for sticking with 98SE.
Again this is MHO, dont flame me cause I have a problem with change.😀
I agree with corky-g you will notice better proformance out of Hardware upgrade versus OS upgrade. I have found XP to be pretty HW hungry so you may even notice slower proformance with the OS upgrade, As I did.
