Hi I am planning to upgrade my pc (Athlon XP 1700+, asus mobo). I am a casual gamer and a performance freak. please help me to upgrade. 1) the very first thing, is it worth upgrading NOW. i hear that intel XE edition of processors with 1 ghz of fsb are round the corner. 2) if i upgrade now should i go in for AMD 64 or intel (915/925) 3) whats are the current market prices of AMD's 64 Fx series of processors and their compatible boards. 4) if i go in 4 intel should i buy an intel original or a chipset board (from asus etc) 5) Are PCI express based graphic cards of any use. Do they provide any performance boost over normal 8x cards.
