64 Bit OS worth it?

[xRyokenx]

I'm debating getting a copy of XP 64bit and was wondering whether there'd be a performance boost or if nothing will work for me? Is it worth it or no?

Depends how much RAM the system is running. a 32bit OS can't use 4GB of RAM (depends on how much graphics RAM you have). If you have 4GB system RAM and 512MB graphics RAM you could only use 3.5GB of RAM. A 64bit OS wouldn't have this problem.

[xRyokenx]

I've got 4GB and a 512MB graphics card, lol. What I'm wondering though is whether or not it will be supported by my drivers, games, and all that. Will it blend? I mean... run?

a 32bit OS can't use 4GB of RAM

This isn't exactly true. Yes, Windows XP 32-bit does not support more than 4GB.

Enabling PAE, Physical Address Extension, extends the physical address size from 32 bits to 36 bits. The OS is still a 32 bit operating system, but now can address up to 64GB IIRC. Applications are still limited to 4GB limit, but more than 4GB is now addressable by the OS.

Linux can handle PAE, as well as other 32-bit windows OS's. Many of the Windows server 2003 32 bit derivatives can handle more than 4GB because it can enable PAE.

I even read in a few places before that PAE can or could be enabled on windows xp 32-bit to allow for more than 4Gb of ram, or atleast address the full 4GB, but the issue is that there are too many poorly written drivers that conflict when the extra 4bits of addressing space open up. But I guess it can be done with PAE, 4GT, and DEP all enabled. But only OS processes can utilize the memory in the last bits as drivers aren't coded to be able to deal with those addresses I guess.

EDIT: And PAE has been able to be used in most 32bit OS's to allow for more than 4GB since the Pentium Pro, so this is nothing new, just obscure. Out of the box 32bit OS == 4GB limitation, but a 32 bit OS isn't just limited to that with the right hardware.
Some 32-bit OS's with support for more than 4Gb straight from microsofts own site (http://msdn2.microsoft.com/en-us/library/aa366778.aspx#physical_memory_limits_windows_xp)
Microsoft site explaining PAE (http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx)
The server versions support PAE, because most drivers made, support PAE as well, while most XP drivers don't.


On topic, I haven't heard very good things about XP 64-bit. Games appear to suffer from what I hear, but I haven't used it myself to tell you first hand experience. But, from what I've heard, Vista 64-bit is excellent, at least compared to XP64, other than it demanding more resources.

[xRyokenx]

Well, look at my spec's, think Vista 64bit would be worth it?

here are two links of "32 versus 64 bit Windows'"

I am using 64bit Vista Home Premium and haven't had any problems with it. I have recently updated to service pack 1 and found that my PC is a bit sluggish but I will be adding another 2GB (4GB total) to my rig. I went over to Vista because I never really liked XP to be honest, looked like crap and felt like crap to me, also has DX10 ;).

[crenn]

Windows XP has Dx10 too! I've found a good defrag made the computer more responsive after installing SP1.

If you only have 32-bit programs, it's not much use to go to a 64-bit OS as there could be a degradation of performance.

[xRyokenx]

I'm really just wondering about how well my games will work. I have a ton of stuff off Steam (but no HL2... go figure), Crysis, CnC3, and Oblivion. Those are what I usually play when I play anything.

EDIT: From what I just saw in those articles it looks like Vista 64 bit is the winner. I'ma go look and see how much that'll run me and possibly upgrade soon. Thanks guys.

I have vista x64. x64 and x86 are the same price. I paid 159 for mine right from microsofts website. Tip: if you download it from the MS website you will get an ISO image of the OS. Do not use Windows to burn the image to the disk since apparently microsoft forgot a key component in the file that makes into an actual CD. Use Nero or another burning program to burn your image, it makes the necessary adjustments to the file so that it can be played as a CD.

Ok,
Some personal experience with XP 64. I would recomend going with Vista, Microsoft is trying to axe XP as quickly as possible (June is listed as cutoff for sales but may be extended), but as a result support for most stuff is very limited, drivers can be hard to find, as most are already looking forward to Vista 64. Not a major difference in games, some shorter load times but most games are 32bit. HL2 x64 has major bugs and no apparent fixes (actually acts like a pirated copy even downloaded through steam).

On the plus side I have found some improvements in stability and some 32 bit games crash LESS even when their support people say that shouldn't be

[Quakken]

Waiting would be a good thing if you want x64. The driver support isn't all there yet, so a lot of your stuff wouldn't exactly work yet. Personally, I would dual boot with xp and a little x64. A the x64 gets better and better driver support, you could make the partition bigger and bigger, and eventually if you find you are having absolutely no problems with your vista installation and all the game and driver support is all there, you could get let it take over your computer completely.

[BerticusPryme]

I have ran both and currently switched to vista ulitmate x64 and to be honest I havent been happier. Runs great,if you run evga boards then the driver support is beautiful. I went straight to the website and downloaded everyone of them. I really recomend it to anyone questioning the upgrade.

[xRyokenx]

It'll be a while before I upgrade as I have things I need to get first (new desk, a car, etc.).

The past couple days I've been realizing how ridiculous prices are. Even when you earn a few bucks over minimum wage everything is still a ripoff. I've been putting things into hours worked instead of dollars spend and for me it's like 5.5-6 hours of work just to get a game that just came out, around 1.5-2.5 hours for a music CD, etc. There's only so many hours every week that a person can work, and there's only so many of those that they actually can work without killing themselves. Prices are way out of it. But yeah... /offtopic in my own thread.

(There's another great name for a store: Off Topic... and not sell emo crap in it either, lol)
