Time for a memory upgrade..

Okay, I now have 2x256MB twimos with CH-5, which is doing very well actually. 2-2-3 @ my current FSB (225), and it also ran those timings fine when I had my old dekstop barton, which ran at 235.

Anyway, it's time to get 1gig, as 512 is getting a bit short in newer games. So I'm gonna get me 2x512 instead, and sell the old ones (already have a buyer).
Now the big question, which ones should I go for? I've been looking for BH-5, but I can't find it anywhere, as suspected.
So I've been looking at the Kingston HyperX series, which looks pretty good.
Kingston HyperX 1024MB 400MHz DDR (KHX3500K2/1G)
- PC3200 DDR Kit w/2x CL2 (2-3-2-6-1)
or
Kingston HyperX 1024Mb 434MHz DDR (KHX3200AK2/1G)
- PC3500 DDR Kit w/2x CL2 (2-3-3-7-1)
The price on these is about the same here. Which of these two should be the best performer? What kinda chips are these modules most likely using? I'm obviously interested in as low timings as possible.
Are there other brands I should look for instead?
Any input/suggestions are warmly appreciated

Anyone here that has some input on the HyperX ?

I think the two to go with is either Mushkin special or OCZ EB 3200 or 3500.
