Ok first off, right now I'm running a 2.4 Pentium, but it's not cutting it anymore. I need a new one that can flawlessly handle games like BattleField 2, Doom3, Half Life 2 etc..... I really have no idea what I want to get, mainly because I'm very inexperienced when it comes to this. I don't want to spend a ton of cash, and I also want to know if I get a newer pentium, if I'll have to get a new motherboard as well (obviously I would for an Athlon). Thanks
