Query: Skip the CPU Upgrade and just buy a new PC!

I wouldn't buy a CPU upgrade for a 486 CPU because when you install it you will still be outdated because you'd only get up to 133MHz of speed, and now they have 800MHz and faster CPU's out. So why waste your money on this and just put it towards a brand new computer. You'll be glad that you did!
