Hello, I have an ASUS P5KC motherboard, which has served me well and still does but I was wondering what would be the best supported processor and the best supported ram in this day and age to put on this motherboard? But of course I still mind the pricing. I just want to be sure what to buy, since I'm not exactly and expert, and if may be more economical, to buy a new motherboard or to upgrade this one up? I still consider it to be great since it can run most of the newer games without bigger issues 
Thanks!
