im gonna upgrade my computer finally and have about 300 to spend on these 3 things. im gonna keep my hdd, psu and video card and upgrade them later in a month or 2. I figured my 500 watt psu should be plenty since its a quality unit and im not upgrading my gpu yet (i'd like a second opinion on this). what would yall recommend? im leaning towards a core i5 and 8gb of ram but am really clueless as far as mobo chipsets go.
