MR816 in Win 7 (64) - Any issues? What's the latency?

Hi folks

I’m thinking of getting a MR816 since my TC Studio Konnekt 48 is giving me a real headache in Windows 7 Pro (64 bit) with Cubase 5 (poor stability, max 256 samples of latency).

So I thought the MR816 might better integrate with Cubase 5 and be more stable and have better latency.

So just wondering what experience other Windows 7 users had had and what kind of latency was being achieved?

I am running Cubase 5 in Win 7 Pro 64 bit, 24G RAM, Intel i7 2.67 Ghz

Thanks for any help!
