I need a GPU that will allow me to use the CUDA features of the mercury playback engine in Adobe Premiere CS5 or 5.5. Here is the list of supported cards from their website:

GeForce GTX 285 (Windows and Mac OS)
GeForce GTX 470 (Windows)
GeForce GTX 570 (Windows)
GeForce GTX 580 (Windows)
Quadro FX 3700M (Windows)
Quadro FX 3800 (Windows)
Quadro FX 3800M (Windows)
Quadro FX 4800 (Windows and Mac OS)
Quadro FX 5800 (Windows)
Quadro 2000 (Windows)
Quadro 2000D (Windows)
Quadro 2000M (Windows)
Quadro 3000M (Windows)
Quadro 4000 (Windows and Mac OS)
Quadro 4000M (Windows)
Quadro 5000 (Windows)
Quadro 5000M (Windows)
Quadro 5010M (Windows)
Quadro 6000 (Windows)
Quadro CX (Windows)

I think I am fairly set on the GTX 470 because it fits my budget, but the fear is that my system would choke the card out.
System specs:

Mainboard : Gigabyte G31M-S2L
Chipset : Intel G31/G33/G35
Processor : Intel Core 2 Quad Q6600 @ 2400MHz
Physical Memory : 4096MB (2 x 2048 DDR2-800 SDRAM )
Video Card : NVIDIA GeForce 9800 GT
Hard Disk : Seagate ST31000340AS ATA Device (1000GB)
Hard Disk : Seagate ST31000528AS ATA Device (1000GB)
Hard Disk : Seagate ST3500418AS ATA Device (500GB)
Power Supply: 480W, not sure on other specs but it seems pretty decent
OS: Windows 7 Home 64bit

The PCIe16 is v1, and seems not to choke out the 9800GT at all (at least my fps in games have been similar to that of reviews I have seen on PCIe2 boards), but the 470 is roughly 2-3x better in the benchmarks, and I dont want to redo my whole platform just yet (waiting for IB next year). But considering I am planning on redoing the platform next summer I had been planning on getting the next gen of nVidia cards for the build, so I want to get a card powerfull enough to get the job done (and sit in this computer when it becomes an HTPC after the upgrade), but without choking the card or spending an arm and a leg on it.

I would also consider a Quadro card except that all I know is that they tend to be a little slower, but much more reliable for production work. I have no idea how they stack against eachother, or against other cards.

Oh, and the video I am editing is 1080p compressed using a modified version of HDVC in an m2ts container. The system has edited several SD projects without any problems, but the HD just brings it to it's knees (reminds me of when I use to edit video on a Pentium 2 lol).

Thoughts, comments, grammar correction, and ideas all welcome :)

lol, ya those quadro cards are crazy expensive and I have eliminated them from my list of potential cards.

Actually my board supports PCIe1 not 1.1, and my 9800GT is a pcie2 card, but the fact is that it is about throughput, not interface level. The newer PCIe2 and 3 support more throughput per lane, but the 580 only uses about 9-10 of the available PCIe2 lanes available to it simply because the card is 'too slow' to process any more information than that per second.
The thought in my mind is that the PCIe1 spec should technically work fine for PCIe2 cards that effectively use 6-7 of the available PCIe2 lanes because PCIe1 spec is half the throughput of PCIe2. So the quetion then is if the 470 would be bottlenecked first by the bandwidth of my q6600, my RAM, or the PCIe slot first. Though you are right, I would have to upgrade the PS to accommodate the new card.

Also, I am debating about doing a minor upgrade of a more modern mobo that will support DDR3 Ram, PCIe2, but still use my C2Q. Then load up on 16GB of 1333 ram, a 470, and OC my q6600 a bit, but that would then delay my IB upgrade later.... But at the same time the projects keep coming and it sucks up too much time editing on what I have. But then the question is if I am going to do such an extensive upgrade then why not go all out and get an i5 and 570, and be happy with that for the next 5 years as I have been with my current system...

decided not to wait for IB or next gen GPUs as current gen equipment will do the trick for what I want to do, and am very very happy with it!
