Well i bought a 2.7 powermac g5 a few months ago and so far its been solid. But i do occasionaly get slow down when playing games like wow or when im using garageband. now i only have 512 ram do you think i wouuld notice a large increase in stability and smoother processing when i up it to 1.5gigs. Would World of Warcraft be alot more better in its processing. Also my computer has been causing alot of heat disapation itno my room would the ram help ease the processors? Another question on my mind is the dual core powerac g5s or the intels going to be so much more better than what i have now?
