Ok, So its been awhile since I fiddled around with new hardware. But its time to upgrade as games are becoming out of my reach. However I want to do it on a budget and not really sure where to start. I need the following and want to get the best bang for my buck. Mother board CPU (quad core?) Graphics Card Ram (is 4 gigs enough now?) Sound card if on board doesn't do it for games still. I would prefer to buy from amazon or newegg and am looking to only spending 400-600 bucks. Any help would be appreciated for this old OSNN member.
