Vertex 3 Question

I recently built a new system and here are the specs...

Antex Twelve Hundred Case
Asus P6X58D-E
i7-970
2x OCZ Vertex 30GB Raid 0
EVGA GTX 580
Corsair 750 Watt PSU...
Corsair 6GB XMS3 CL7

Note everything is stock and using XMP to get full RAM speeds....
My question is that I am looking into going to a single Vertex 3 SSD 120GB drive ($250 respectably) when released and looking at the sequential read/write speeds of 500/500 and loving it!

Reading that review, and verifying that the motherboard DOES have a marvell 9128 which runs through a single PCIe 2.0 slot, I will get maximum speeds of 400MB/sec realistically...
Is this true that this drive will 'be too fast' for my SATA 3.0 6GB/sec equipped motherboard?

Main reason I want to get rid of my RAID configuration is because of the speed draining. I used to get 460MB read speeds at first and now it's all over the place maxing around 300MB or so after useage. I have the latest firmware and am aware of garbage collection and leaving it there to do it's job, but who has time for that crap? I want TRIM and something much faster. Also the WEI went from 7.5 to 7.3. The system is still responsive but I prefer a single SSD that does the job even quicker and more efficiently. Note I still love these small vertex Drives but want to fully take advantage of my system specs (Sata 3.0)...

Thats a screenshot with this drive performance on the Marvell 9128 chipset (which puts the Sata 6GB/s line through one PCIe 2.0 lane)
Look it up and PCIe 2.0 has a maximum theoretical throughput of 500MB so in reality it's 400MB which is exactly what that benchmark shows...

Sorry, this article is right... everyone with an X58/P55 is stuck at the slower speeds and this drive here surpasses our motherboards.
Expect ~400MB reads and ~250Mb Sequential speeds
