Which memory to go for?

[gitara]

Hi, I need some advice regarding which memory I should go for,
should I buy;
Cas 4 6400 (Corsair Dominator Twin2X4096-6400C4DHX) or the
Cas 5 8500 (OCZ 4GB (2x2GB) PC2-8500C5 1066MHz Dual Channel Platinum Series DDR2 (OCZ2P10664GK).

How high would the Corsair oc? Will it go up to 450?
Which one would be faster and would I see any real difference?

Also the Corsair is about 20% cheaper (in Belgium) than the OCZ

Depends on your other specs. What motherboard/CPU? Asus motherboards don't like OCZ RAM. Depending on how far you're planning on overclocking you may be best off getting faster RAM. There's no definites about how far any RAM will overclock, so probably but no guarantees.

If your stock FSB is 1333 then any o/c will start o/cing the ram so you would probably want faster ram; if it's 1066 you might not need faster ram, depending on how far you're planning on o/cing.
