Alright. In my computer right now, i've got: CPU: Intel Pentium 4 550, "Prescott", 3400 MHz Motherboard: Intel Battle Lake D915PB1 RAM: 2 x 2gb Corsair XMS2 Video Card: Nvidia Geforce 9600 GT My question is, would it be worth the money to upgrade to a new Core 2 Duo processor? I use the computer really only for gaming. Would I see any real difference in performance if I were to upgrade to something like this? I know that games are mostly dependent on the GPU, but I've had this processor for a number of years now, and I figure that it's about time to upgrade. Along with that it runs REALLY hot. Like, 63 degrees idle hot. Anyways, what do you think? Is it worth the bucks to upgrade? Another, somewhat unrelated question to that first one is more general, and just something I would like to know out of curiosity. What difference does your motherboard make? I mean, ok, some come with more or less RAM slots, or slots for two videocards or whatever, but in general, what difference does it make? I'm sort of a noob if you can't already tell, so this is just something I got to thinking about as I was writing this post. Anyways, if anyone would like to enlighten me with regards to that point as well, that would be great.
