Those who may remember, about a month ago I was trying to figure out what was wrong with my old PC. Until now I still do not know what is wrong with it, so I'm giving up and deciding to just build a new PC. It's been a while since I last put one together, and even the last time I did, I had help (as I am this time as well). I will be mainly using my PC for play WoW, watching movies, internet, and daily assignments and such for school. Playing WoW will probably be the most stress I'll be putting on my computer. With that said, this is what I've came up with after researching a few days on various sites. PSU http://www.buy.com/prod/corsair-hx5...lar-atx-power-supply/q/loc/101/203270716.html $108 Motherboard http://www.newegg.com/Product/Product.asp?Item=N82E16813131142&ATT=13-131-142&CMP=OTC-pr1c3watch $147 CPU http://www.newegg.com/Product/Product.aspx?Item=N82E16819115003 $339 RAM http://www.newegg.com/Product/Product.asp?Item=N82E16820145590 $175 HD http://www.newegg.com/Product/Product.aspx?Item=N82E16822136073 $152 Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E16814130082 $309 LCD Monitor http://www.newegg.com/Product/Product.asp?item=N82E16824009102 $296 CPU fan http://www.newegg.com/Product/Product.aspx?Item=N82E16835118003 $57 Total: $1583 $80 in mail-in rebates I will be reusing some old components such as my Antec Sonata Case, DVD RW (may need to upgrade since it's only a 4x speed), keyboard, mouse. I have have an extra 120gig WD HD. It's a bit old though so I'm not sure if it will work in my new PC I'm building? Same thing with the Kingston 2x512mb sticks I have. I'm also upgrading from a Radeon 9800 PRO which I know is really really old in comparison to the video cards now. I'm just a bit unsure on my selections. I'm unsure if my PSU will be too much, or perhaps too little? I hear having a good PSU is extremely important and to not go cheap. I'm just not sure what is cheap. I checked reviews and the OCZ had really good reviews. As for a HD... I heard WD is king. Seagate got good reviews though, but sounds like there were little problems here and there. I really only need about a 250gig. I can also get more later I guess? I've always wanted a 22" LCD screen. Why the 22"? Because going any higher then causes the price to go up a lot. Just seems like the best bang for the buck type deal. Anyways... I am hoping in ordering they parts later today. Really when I wake up but I'm willing to wait in order to insure I'm getting the right parts for what I am planning on using my PC for. I just want to make sure I'm building my computer right this time around. I want to make sure my computer doesn't suddenly stop working because I may have overlooked something like not having enough power, or too much if that is possible. I'd really appreciate any type of advice or comment. Upgrades or Downgrades I can make to fit the needs I'm going to be using my PC for. Like I said, it would be mainly for Gaming and playing World of Warcraft. edit: I wanted to keep this around $1200-$1300 so it would be nice if I could get some parts for cheaper... checked newegg.com, pricewatch, zipzoomfly.com Not sure if it's advise to use better thermal grease than what the CPU comes with. I have some artic silver 5 laying around. Fan and heatsink wise I'm on not sure if I should upgrade from what I have in my case? Never really built a computer as massive as this one, so I'm not sure if it will need any type of extra cooling. Quieter the better as well as long as it doesn't get too expensive.
