Lag with Blackmagic Intensity Pro

Question

I just got Adobe Prod. Premium CS6 as well as a Blackmagic Intensity Pro monitoring card and an eVGA GTX570 graphics card, and to avoid problems, I did a new Windows installation from scratch on a formatted drive. This was done today, so all the drivers and program updates are completely up to date.
I know the Intensity Pro is about the cheapest card you can get to preview video correctly on a TV set, since graphics cards don't display video in the same way as a dedicated editing card does, so I'm still happy with it, but I would like to find it if I can get around this annoyance until I can get a better card, or if perhaps it's a flaw in Premiere and a more expensive card would not make a difference.
The card has about 200 miliseconds of lag compared to the program monitor in the Premiere window. This is not really terrible, but it becomes distracting when watching the TV screen and the change of frame in a cut happens first in the computer monitor in a small window within Premiere, and a fraction of a second later on the TV screen. Also, it makes it difficult when I have to sync cuts to changes in the music. I guess in that type of situation it would be better to do the cuts on the computer monitor and then switch to the TV set for color correction.
But this is not just in regular playback. It gets worse when scrubbing the timeline, or moving with JKL. In those cases, sometimes it takes it like a second to catch up to what I see on the program monitor.
I also have a GrassValley HD Spark monitoring card for Edius that while it has a little lag, it's much shorter than this and it's not so distracting. That card was connected using the same cable to the same TV set, so that tells me the Intensity Pro has some extra lag, but it's hard to complain about it on a $190 card. However, I was wondering if anyone here has found themselves in the same problem and found a solution? I searched but so far I couldn't find anything.
And as far as these type of cards, what is the least expensive one that will give me perfect preview with no lag?

Answer 1

Thanks, I might try that one, although it's a bit over my budget at $660.25, but I'll have to if I don't have a choice.
What about the Matrox MXO2 Mini, has anybody tried it?
About turning off MPE GPU's acceleration, that is not an option for me. I'm used to edit in Edius, where almost everything you do is real time and you barely have to render anything ever for previewing purposes, and Edius doesn't even require an expensive Nvidia card for that, it only uses the CPU. But, it lacks several features Premiere CS6 has, especially when it comes to artistic effects. Overall I'm really hooked up on Premiere CS6, but only if I can have the same fluidness of work I always had with Edius, so I wouldn't turning off MPE. That's why I spent $280 in a new graphics card.
I really hope that this is just a matter of the BM Intensity being a cheap card and not Premiere, because this past couple of days I've been editing almost all day and while I enjoyed the editing process in Premiere, it's very frustrating to start playback and sometimes it will be fine but other times the audio and video will be out of sync, so I have to position the playhead back and start playing again. When that happens half the times you play something, it's really annoying. This is regardless of real time areas or not. To make sure of this, I forced render of an area that had no effects on it and it still has the sync problem. I had to disable auto playback after rendering because that would cause the problem every time, while if I position the playhead manually and then hit play, sometimes it happens, sometimes it doesn't.
