What Aplications for a new build

Well, the very first and most critical program I would suggest is a Windows XP installation CD. After that, of course you will need the install CD's and drivers for all of your hardware, past that point it's kind of hard to tell what you need until you need it and don't have it.

well i kinda figured the operating system and the drivers....

for the drivers do u recomend going to like the nivida website for there drivers or evgas

also what programs should i download for checking my temps and stuff.

XP, Service packs, mobo drivers, nvidia/ati drivers (depending on your graphics card), WinRAR, Daemon tools, uTorrent, PowerISO, Speedfan, Atitool, Fraps, K-Lite Codec Pack (comes with Media Player Classic), Messenger, Office, and games.

I install those apps in that order every time I format a PC.

7-zip is a great alternative to winrar or winzip and it is free.

After OS, first thing should be Anti-virus and Firewall, then an adware killer like Spybot Search and Destroy and/or AdAware. Load all critical OS patches, but be warned, Microsquishy has flagged IE7 as a Critical Update, so always choose Custom and de-select it until you know your apps work with it.
Speedfan is good for checking mobo temps and voltages, or the nVidia Control Panel / nTune for your GPU.
Get Acrobat Reader (www.adobe.com). You may want Shockwave Flash. You don't want Real Player or Weatherbug. Sometimes a convenience, add-ins like Google Toolbar or Yahoo Toolbar also cause problems. I would suggest avoiding them. They come bundled with other programs (e.g. with Acrobat Reader) so be sure to unselect them unless you know you want them. You're not a pirate, so you don't need a P2P client that likely contains malware anyway.
Who is your ISP? Many provide security software, e.g. Comcast uses McAfee, Frontiernet uses CA, etc.
Open Office (www.openoffice.org) provides a free alternative to paying Microsquishy for Office. Mozilla's Thunderbird email client is a viable alternative to Outlook Express.
Finally, if you anticipate having lots of time in the future, download the Guild Wars game client :-). Have fun.

Second that, works great for me.

Depending on the amount of RAM you are getting with your system, I'd look into 64 bit vista or xp if you have not purchased your OS yet. As many have already mentioned antivirus is critical. AVG provides a nice free antivirus solution, also panda 2008 beta is available as well. If you want to pay for one I recommend nod32, is very light and works well. I've been really into defrag recently and after advice on these forums purchased a copy of diskeeper, real time and much better defrag and the windows tool. For the spyware, you can use Windows Defender which is free, or if you don't like that people above have mentioned Spybot and Ad-aware, both very good and free. I'm not a big fan of personal firewalls because depending on the complexity of your home network can be a hastle to setup trusted programs, zones and computers. Chances are that your router at home has a hard firewall built into it which is better to use. If you really want to run a firewall IMHO BlackICE is the best. Some users mentioned 7zip as well which is great ^_^

can't do without nero, powerdvd, some kind of p2p program, everest ultimate, startup management program, some kinda of voip (teamspeak, vent, whatever), i think that is about it...some opther handy stuff to have around, core temp, cpu-z/crystalcpuid/z, orthos, speedfan, atitool/rivatuner, 3dmark, mirc, frontpage (its handy to have, plus, most office stuff you have to get FP seperate), netlimiter, winamp, i think that is a more definite list...
