800 or 1066 for this cpu/mb

[Nextogen]

I read about this DDR2 800Mhz vs. DDR2 1066Mhz thing but I just need to see if someone (who, maybe, have this mb and cpu in his system) will give me a good advice and help me decide.

mobo: Gigabyte GA-P35-DS3R
cpu: Intel C2D E6750

Maybe I'll OC later on, but not for the moment...

Some of the RAMs I was thinking about (I'll get 2gb):

■Kingston HyperX 1G DDR2 800 CL5 Kit 64MX64 Non-ECC 800MHz 240-pin Unbuff. DIMM 1.95V
■GEIL 1GB PC2-6400 DDR2 800Mhz Black Dragon, 4-4-4-12
■GEIL 1GB PC2-8500 DDR2 1066Mhz Black Dragon, 5-5-5-15
■OCZ 1GB DDR2, 1066MHz Reaper Heatpipe HS/CL5-5-5-15 /Kit

The main question: is 1066 worth it?

Fill free to suggest which memory would you use.

Thanks

■GEIL 1GB PC2-6400 DDR2 800Mhz Black Dragon, 4-4-4-12
■GEIL 1GB PC2-8500 DDR2 1066Mhz Black Dragon, 5-5-5-15

I bet these two are the same chip one with higher timings and faster clock the other with lower timings and slower clock.

I would go with whichever of these two is cheaper...

both 4-4-12 and 5-5-5-15 are good but i will choose 4-4-4-12

Sorry for being indefinite. I thought about it and I think, when the time comes, I'll just upgrade to 4Gb.
