Hi guys,

       I am considering purchasing a brand spanking new Alienware Aurora desktop.  My current configuration is looking something like this:

-Intel® Core™ i7 930 Quad Core Processor (2.8GHz, 8MB Cache)

-Single 1GB GDDR5 ATI Radeon™ HD 5870

-6GB Triple Channel 1333Mhz DDR3

-1TB - SATA-II, 3Gb/s, 7,200RPM, 32MB Cache HDD

      The rest is not very important.  I've read up on the dell support site which states you can overclock your Alienware Aurora automatically by following a few simple steps in the BIOS and choosing a 'Load Level 1 OC Setting' option.  I have never overclocked in my life so its either using the automatic overclock feature or staying at stock.

1) Is the 'Load Level 1 OC Setting' option 100% safe and there would be no need to check the voltage and heat?

2) I've read that it is recommended to have 1600MHz ram to compliment an overclocked i7 CPU.  Will my 6GB Triple Channel 1333MHZ DDR3 work fine with the Level 1 OC Setting?

3) Exactly how fast is the i7 930 Level 1 OC Setting and the i7 920 Level 1 OC Setting?  Which is the better buy?

Please help
