I got done with building my first computer a while ago and I realized that some of the parts on it are not exactly good enough for what i want to use it for. It contains, -A terribly cheap in quality Chaintech P4 mobo cost me 89$ and i regret it -Intel Celeron 2Ghz processor with stock fan -80gb western digital Serial ATA harddrive -Some unknown used DVD Drive -256mb pc2100 kingston DDR-SDRAM -windows xp professional -400watt powersupply -1, soon to be 3 case fans with 4 dollar exaust card through pci slot in back. I was leaning towards upgrading processor so I can get faster ram (pc2700+ without overclocking) Is this all i really need to make this into a gaming machine? and by the way- I dont want to overclock at all... even if it means paying more. For gaming and school use, should i even bother spending double to get 1 gig of ram or should 512mb be enough? I want to get a 167 dollar P4 2.8ghz proc. with 800mhz fsb and 1meg cache, would that overheat easy and if so what should i get for cooling if i were to upgrade my processor? Thank you for hearing me out... if you have anny suggestions please let me know.
