ddr2 800 worth it?

[bee]

just about to go conroe, when i can source a chip

just wondering if gettin some ddr2 800 is worth it over some ddr2 667, the most i'd ever want for overclocking is 400fsb (ddr2 800) ,but couldnt i just clock some ddr2 667 ram to 800?

if so what cheap ddr2 667 is pretty much guarenteed to hit 800?

only looking for 1gb for now but ive been looking at -

ballistix 1gb (1x1gb)ddr2 667 for £66
patriot low latency 1gb (2x512mb) for £70
Corsair 1GB (2x512mb)DDR2 Value Select PC5300 also for £70

any good?

what do you think of the ballistix then,DDR2 PC2-5300 • 3-3-3-12 ,seems to have a lot of headroom for the overclock and is the cheapest and is only 1 stick so when i get some more memory around christmas will still only have 2 sticks instead of 4.

its not like the normal ddr ballistix is it?,that dies after 3-4 months ,i had some of that
