Just thought i would drop a quick post to say i solved my problem from this thread here http://www.nvnews.net/vbulletin/showthread.php?t=83920
simple as sacking the 96.89 drivers and installing the 93.71s .
Difference was huuuge.
CPU score 6534
everything set stock across the board
Pretty happy with that..no its onto some serious gaming and worry about overclocking when i need it as with the other drivers (or corrupted install off most likely) i was looking to overclock when it didnt need it.
cheers for those who jumped in with suggestions
