Microsoft Windows XP Professional SP2C 64-bit for System Builders - OEM

Pros: Without a doubt by far the most stable version of XP I've ever used, Windows XP x64 is probably the pinnacle of XP in all of its uses. I've been using it myself for nearly two months now, and without skipping a beat, I manage to find all of my drivers for it, (For rather exotic cards as well: The Asus PhysX card, along with a 9800 GT) As well as a humble card reader. The only driver I couldn't find was for an elder NAS that is about to be replaced anyway. x64 bit computing is without a doubt more stable and feels almost twice as fast. This system was built new fom the ground up, but its Snappier thanks to XP x64. The jump from x86 (32 bit) to X64 isn't as big as I thought. I can see all the ram I could ever need now... All 8 gigs, nevermind the extra 512 MBs in my graphics card.

Cons: Internet Explorer 64-bit is nothing to Minefield 64-bit (Firefox), but without compatible flash both are somewhat lacking... Finding A Firewall and Antivirus was somewhat of a challenge for awhile, but a quick google search liquidates all worries. (I'm using Avast Anti-virus, and Comodo Firewall) Graphics Cards Monitoring software (Ntune, And the ATI Equivalent) don't seem to function but Riva gets around that. Crashed for about a week until I noticed my Graphics card was too hot, and Riva fixed that rather quickly.

Overall Review: Without a doubt, my most iffy part of the purchase of a new computer, I now don't regret it for a second, and don't ever wish to go back to x86 (32-bit). Searching for 64-bit programs is fun, but if you can't find them, simply get the 32-bit one, it will almost certainly work fine. It will be a dark day when I can't find something to get around any sort of trouble this Operating system is supposed to give users. I've heard more ill-will versus Vista and Especially Vista x64 then this x64.

Pros: I went to XP64 after a long stint on Vista 64. I just like XP better not a huge knock on the Vista 64 ultimate I had running. It has run all my programs other that Cisco VPN. Also seems less resource needy as Vista.

Cons: Maybe it's my imagination but it seems to load slower than Vista did. Also, I added a 2nd SATA drive after my initial install and my usb devices locked up. I reinstalled the OS after adding the 2nd disk and have had no issues since.

Overall Review: I have had a pretty good going since the revert to XP. I am happy so far. I kinda worry about directx10 games down the road but maybe Vista will mature by the time its SP2 rolls around and I can always reload it. Also, to the reviewer below, AVG makes an awesome anti-virus program for free!! It usually ranks ahead of Macfee & Norton in reviews

Pros: 64 Bit is the future. It is extremely stable, extremely fast, and extremely beautiful. I have not experienced one single problem. All my programs work, all my drivers work, but best of all. Crysis runs full gfx in DX10 wonderfully.

Cons: $139.99... I bought is for almost 100 dollars more back in August '07.

Overall Review: Love it Love it Love it.

Pros: Installs like windows always installs. I put this on a machine built by cyberpower pc. THey did not offer xp x64 so I had to order it. I had no issues with the install.

Cons: be sure you have x64 drivers for your devices

Overall Review: I had to make sure i had drivers for my various components that support x64 - this is not something a newbie should mess with. Some things just do not work with x64. But now my adobe photoshop and lightroom run much faster than before on standard xp and it recognizes 8gig of memory.

Pros: Great operating system, very stable, fast, 64-bit.

Cons: Most games aren't "supported," though they usually will still work (i.e. COD4, CNC3, etc.). However, iTunes does not support xp64, only Vista64 (though there's an available hack to make it work). Zune's not supported either, and I'm not sure about any available hacks, as I don't own one so I don't care to try. Shouldn't be a problem though, as Winamp supports Zune, iPod, and most other generic mp3 players, and is 64-bit compatible. Basically, it's just really annoying to try and get programs to run correctly.

Overall Review: I suppose the biggest plus from buying this system is that I've learned a lot about my computer through trying to make everything work! I'm glad I bought 64-bit, though I may break down and buy a 32-bit version to dual boot for those difficult programs.

Pros: Windows XP is rock solid, unlike their latest product. XP 64 bit is faster and takes great advantage of up to date equipment. Installed quickly and easily. Recognized MB and 8 Gig of ram immediately. Works great for video editing.

Cons: None.

Overall Review: Hardware and software industry is beginning to catch up with the 64 bit technology. Drivers can be tricky but no big problem. I use DriveDetective to help in the installation. I plan on getting a few more licenses before they take this off the market and we're left with nothing but 64 bit Vista.

Pros: I downgraded from Vista Ultimate 64 and the results are very noticeable! When I would boot up Vista (with some basic programs like AVG, Steam, wireless utils, Ati CCC, etc) I would be using about 2GB right off the bat. Not a problem for me since I have 4GB, but it made my system feel slow. (Q6600 @ 3.2, HD4870, 640GB (OS) and 2x1TB RAID 0 (storage) - a high performance system) Now with XP when I boot up fresh I'll have about 750MB in use, and right now with a bunch of programs open I'm using 1.26GB. BIG improvement on system resources! DX10 is not a big concern to me right now, and I didn't want to jump on the Win7 boat just yet as it's still a very new OS.

Cons: no dx10, and a few minor things here and there, but the benefits to me far outweigh the detractors and definitely not enough to mark it down an Egg.

Overall Review: I think it's a good idea to have a legit copy of XP handy, especially for any older systems or ones with limited resources (like a netbook). Vista has its ups and downs, and there admittedly are SOME things I miss about Vista, but overall I'm much happier with XP!

Pros: Excellent OS. Very fast using photoshop CS especially with more than 4 gb ram

Cons: None

Overall Review: Great with photoshop. I use 8 gb ram with excellent speed on addition of filters.
