I have just bought myself some new kit from OcUk - and I was wondering what kind of advice you guys had for me to start off overclocking it 
4400x2 AMD64
7800GT 512MB GW Bliss GLH x2 (for SLi)
Abit AN8-32X
Corsair 2GB DDR XMS3500LL Pro TwinX
ThermalRight SI-120
I haven't really o/c'd since waaaay back in the early 90's when I first overclocked my AMD DX4/100 to 150 (stable!)
But I'm not a complete numpty
I was just wondering what ideas you guys had that were 'safe' to start off with on this combination of kit.
Any advice would be much appreciated.
