What Ram for my Rig

[leveler]

Hi All

I'm starting to get my gaming rig together, based around a Abit AB9 Quad GT with a q6600, 2x Raptor 150 GB, 2x HIS ATI Radeon X1950 Pro ICEQ 3 V2, Antec P190 case, cooling- not sure yet. The only thing I'm stuck on is what ram to go for, my priority at this point is speed without overclocking so what's your opinion based on experience.

TIA

LeV

Crucial Ballistix.
G.SKill HZ is good too.
In fact there's a small list of known compatible RAM in Nelly's QuadGT FAQ thread.
