Fat, Drunk, and Stupid is no way to go through life Son.
it would allow you to lock it in the BIOS - without it, your AGP slot is running at 100Mhz vs what its supposed to (66Mhz), and your PCI 66Mhz (vs stock 33Mhz). Now that will give you more performance, but you can also damage your hardware doing so, and an AGP/PCI lock will lock those bus speeds, allowing you to overclock more while foregoing the chances of damaging your hardware.
How about Dfi nf2 ultra infinity $93.00 @ newegg. Most overclockable Amd motherboard made! Look at reviews of this board,almost everone who has reviewed it has achieved the fastest clock speeds they have ever encountered using Amd platform. Of course you must use top of the line memory, I suggest Ocz 4200 el with this board for max performance also must use 1-21 beta bios to allow max performance of memory. Take a look here.Good luck! http://www.cluboc.net/reviews/motherboards/dfi/LANParty...
