I've just got a new PC with Vista (Home Premium), it struggled with a gig, so added another 3 gig (literally just this morning) and it flys!
I've got 3.5gig in there (had 2x512 before), it's showing 3325Mb (/1024=3.24Gb)... 99% certain it's the 32bit version (unless it just doesn't say anywhere that it's 64 bit).
Overall, I'm actually surprised - I quite like vista, some of it is very annoying (yes I am fuckin sure I want to do that... stop fuckin asking me!), but only had one program not work (an ancient screen recorder) and no driver probs. It does hog resources but with ok hardware it's overall no worse than XP... and it seems to be better at managing memory.
I wouldn't have bothered with it on my old pc (P4 2.4Ghz, 1Gb), but quite happy with it on this one (Core2Duo 2x1.8Ghz), can't see any reason to load xp on here.... yet.
Like it or not, most of us are going to have to use it sometime and it's certainly a lot better than when XP first came out and nothing fucking worked!
I just got a new laptop a week and a half ago, and I totally love it.
XP Home Premium, just 2 gigs of ram, a 1.8 Core 2 Duo, and a decent vid card... It flies for me, seems MUCH quicker than XP and I have Glass enabled, so it looks way better.
With all of this, I can still multi-task like a crackhead and it doesnt bog down... At any given times Ill have 20 tabs open in FF, with all my extensions, aim, thunderbird, uTorrent, Xchat, Photoshop, Dreamweaver, a media player, and Word. Nothing slows down with all of that, and it's great.
I did hate the "Is it ok" messages, but figured out how to disable them for good, and since then it has been sweet!
Peep This:
Windows Vista Tip: Disable annoying "Need your permission to continue-" prompts
I did it really easily, and like i said, no more warnings or promts or whatever the hell you want to call them.
Also, the other day I downloaded a torrent and when I opened the RAR Windows told me there was a trojan, and let me delete it.
WINDOWS actually knew something was bad... I didnt know M$ was capable of that. haha
Oh, and to adress the memory issue... There is a 4gb limitation on normal PC's. It has been like that forever. But, some versions of Vista support more... Theoretically anyways... I believe Vista Business Ultimate can support something like 160gb ram.
But your hardware can't. Unless you run a server.
The issue of having 4 gb. and seeing 3 is because there is hardware memory allocation... Your HD, your CPU, your Sound Card, your DVD/CD Player all need RAM, So it is allocated. Your video card also uses plenty of it. So if your video card uses 512MB, And another 250 for all the other hardware is used, you will see about 800 or so MB missing... It is just PRE allocated. It has always been like this, but in this case it just shows you what you have AVAILABLE to use for whatever, instead of saying you have 4gigs and you find out when using some crazy ass programs that you can only use 3...
Read up on it. Itll clear it up. Just because it says 3.3 gigs when you have 4 doesnt mean you are getting less. It is using it just as it would any other version of Windows, it just tells you that its doing it this time.
