I am looking to build my own computer in the near future but this being my first time I am unsure of what components to put in. Please if you have recommendations would be great. First of all This computer is for gaming so I have put it in this section: I have allowed a $500 - $600 (US) budget for my CPU And GPU what is the best in regard to Performance/Price Sound Card - Not sure recommendations welcomed Hard Drive - Is there a big performance difference between a 5400 and a 7200? and is it worth the extra money. OS - I am sorry to say but Windoze XP SP2 (any where cheap?) Display - I am looking at 22" Widescreen Unsure what Brand what is best? that is the stuff I am stuck on if you have any other recommendations that would be great. P.S I am a Nividia Fan so please no Ati thanks.
