Ok my problem is that i have a Hp 9870 and I want to upgrade it. I need more ram and I have no clue if Pc-800Mhz will work or the even newer modules of pc-1065 or something MHZ (RDRAM). I would also like a new P4 CPU and I need too know what GHZ will work up to the max the motherboard will hold. As well if any of you know, what Video card can my motherboard support up too??? i really want a GEForce FX video card and will 8x Agp work? If any of you who is reading this and have the same computer or know someone who has upgraded there's please tell me what I can do to improve my crap machine.
