About memory frecuency and a new PC

[maxrebellion]

Hi, I'm waiting for the new sandy bridge extreme edition processors to buy a new pc, and for now I'm planning the components. From what i have readed these processors will support up to four DDR3-1333 memory channels.

If I buy for example DDR-1600/1800/2000, will increase performance? What would happen if I do so? Should be 1333 only?. What can i do to improve this section?. And finally, any advice in general?.

Currenly these are the components:

- Core i7 3960x / 3980x (if finally true).
- 6x 4GB DDR3-xxxx. Rest pending.
- Motherboard pending.
- Nvidia GF GTX580 / GTX590
- Soundcard. In principle the same I have now (SB XFi Elite Pro).
- 2x OCZ vertex 3 SATA3 RAID0 as system partition and main workplace.
- 2x Seagate 2TB SATA3 7200rpm 64MB cache as generic storage partitions.
- 1000/1200W power supply. Rest pending.
- Tower, cooling, peripherals, ... pending.

Help! thanks

Faster RAM will always run at slower speeds. The faster RAM will allow you to overclock above the 1333 Mhz. speed which shows a small performance improvement, but not much. You really don't need a 1000w PSU. A 750w should be plenty.
