5D MKII + 32GB CF speed : Transcend 133x Kingston 133x or Silicon Valley 200x ?

With my 5D MKII I think i can take pics fast enough one after another and also HD movies seem good enough, I have some questions :

Is 133x the fastest a 5DMKII can use to write pictures to your memorycard?
Cause I know the camera itself has also it's limitations, it has no point buying the fastest most expensive card if your camera can't save so fast, this is no camera that has UDMA capabilitie's for example.

I'm looking for a 32GB card and I thought of :
- Transcend 133x
- Kingston 133x

I also found a less known brand "Silicon Valley 32GB 200x CF" for about the same price, are there any reviews about Silicon Valley cards, as I didn't find any on Amazon.
Sandisk is too expensive for my needs and I never had any problems with Transcend, I know Kingston is also great (had SDHC cards of them in past).

I can't say anything about the write speeds of the 5Dm2. I get the faster cars so I can dump them on the computer faster. I've only used Sandisk. Lexar is supposed to be up there right beside them, and I wouldn't mind trying Transcend. They seem to be on sale the most. I know people that have had problems with Kingston. I don't know if I could trust other brands.

BTW, a lot of stores are clearing out the "slower" speed cards for the new 1000x cards. You might want to ask your local store if they're clearing out the old cards.
