Hey guys first post on here. Anyways the other day me and my friend took his dads old computer apart (the MOBO was fried on it) this computer was probably bought a few months before vista came out so it has 1 gig DDR2 ram 80 gig SATA harddrive 300 watt power supply and a DVD rom and also it has windows XP, so i was just wondering since i do a little gaming (World of Warcraft, minecraft, League of Legends, Heroes of Newerth) nothing fancy but still some demanding game. So my question is is it a good idea to go out and buy a new MOBO with a CPU and grab maybe 3-4 gigs of ram and a graphics card or just save and buy a whole new system. Thanks ahead of time for your responses.
