I want to build a new PC and I've a little question about processor speeds I hope someone can enlighten me on. I'm thinking of buying an AMD Athlon 64 3400+ running at 2.2 GHz to go on an MSI K8T Neo-FIS2R motherboard (or should I go for an Asus K8V Deluxe maybe?). How does the chip stack up against the similarly-priced 3.2GHz Pentium 4? Is the Pentium literally faster by 1 GHz? Is this not a fair comparision? Should I be looking at other things too? Most of my stuff will be web browsing with a bit of movie watching and video editing and perhaps the odd game such as Call of Duty.
