Thanks for the help guys,
The new NForce 2 does look good, and will probably wait for that.
As for my 3dmark2001se score, 8700ish with out any clocking of the vid card. close to 9500 with clocking the card.
Motherboard OC'ing... cant be done, running a Intel D850GB board, no oc features. Also think that is why my system is slow compared to a similar spec machine on say an Asus board. Intels memory timings are not agressive, and geared towards 24/7 stability (Which it does day in day out)
Thanks for the post regarding the 423 -> 478.
http://www.upgradeware.com do one as well, but that like the powerleap is not available in the UK just yep. Might order one in from the US, but after the cost of the unit + postage and then the new CPU it might be cheaper to actually buy a 478 board and cpu and utilise my exisiting parts.
Thanks again for the help.
