I'm getting ready to build my own computer and I was looking at CPU's and noticed that 3 ghz prescotts have 1mb l2 cache but people have mentioned it gets rather hot, while the northwood 3 ghz have 512bk l2 cache runs much cooler but has a smaller cache. So i was wondering if its still better to go with the 1mb cache and maybe buy a new fan and heat sink for it?
