Which is better for overclocking?

Ive currently got 2 gigs of the 6400 DDR2 GeiL Ultra 4-4-4-12 stuff and they are running fine and was planning to upgrade and buy another set but have come across this 2 other offers :

and:

G.Skill 4GB DDR2 PK PC2-6400C4 (2x2GB) CAS4 Dual Channel Kit (F2-6400CL4D-4GBPK)

Package : 4096MB kit (2x2GB) dual channel pack

What do you reckon will be best? I can always flog the GeiL ram if needed.
The higher rated ram has got worse timmings and the lower rated ram has got as good timings as my geil.

Thanks a lot

G.Skill 4GB DDR2 PQ PC2-8000C5 << this have been getting really good reviews recently.
for the price would say they are a steal.
"The higher rated ram has got worse timmings" Check this thread, ppl getting a lot better timing than stated

the pc 8000 would certainly give you more headroom for oc'ing. wouldn't get in the way of high fsb's if you can get that far.

Sounds like I am going to go for it then. I will probably get around £30 for my Geil set
