This CPU has a great cost/performance ratio. While I do not overclock, it runs at 3.17 Ghz on an ASUS P5Q mother board with 4 gigs of CORSAIR DDR2 800 speed ram. While I did not have any problems loading Vista Home Premium, if your verson is not SP-1, then only have 2 gigs of ram onboard at the time of install and do not increase it to 4 gigs until SP-1 installs. Also, the P5Q series of mother boards is very new and while it does take advantage of all of the features of the Intel E8500 CPU, one of the first things you need to do is upgrade the BIOS to the lastest available from ASUS. With these cautions, you will have a blazing fast system that is in a moderate price range.
