hi everyone.. been a little while since i last posted anything. It seems ever since i got my old skool quattro, my computing days have taken a bit of a 'back seat'

.
anyway.. not spending much time or money on PC's much these days, however, I was given a free ASROCK K7VM2 rev 3.0, complete with an socket-A Athlon 2200XP. The chip has been Over clocked to an 2600XP by the previous owner. and runs almost perfectly (except on very hot days of the year

)
Thing is i've now also been offered 'for free' a sempron 3000+. its 'socket-A' and so i am told will run on a 'rev-3.0' ASROCK K7M2 like mine.
My question is: What will be faster? sempron 3000 or my overclocked Athlon XP?
As i understand it, the sempron 3000 socket A is a 'Burton' chip.
so where as 'most' socket A sempron's are slower than there Athlon rivals, will the 3000 actually be faster? And also, how much overclocking headway do i have with the sempron 3000?
sleepy now..
lol
