I agree. I have Striped raptors on my FX60 machine, will have Striped VelociRaptors on my Phenom II system I am building this weekend. (If I can get my water block adapter in time 8)
If you don't have them, BUY THEM! They will make a good system great and will bring new life into an old system. If you are on the fence on when to upgrade, just buy the Velociraptor. When you figure out what you want to upgrade to, just move it over and BAM! WOHOO.
