Recommended low profile graphics card

Before buying the graphics card I wanted, I made sure to check that it was compatible with my computer... which it is not.   Thankfully, that saved me a wad of cash and a bunch of time. However, I'm in a new dilemma as now I'm not sure what graphics card will run well with my computer while being a decent card. I'm currently running this:

Dell Inspiron 530S (Slim)
Processor: Intel (R) Core(TM)2 Duo CPU E7200 @ 2.53 GHz 2.53 GHz
Memory: 3.00 GB
32-bit Operating System

The problem is that because it's a slim case, my graphics card options are limited. I'm also unsure about its wattage so I don't know what will run smoothly. I've done a bit of research and low profile cards seem to be the only things that work with it. So far I've gathered that the following are recommended low profile cards:

- 9800 GT
- 9600 GT
- NVIDIA GeForce 9500 GT
- 4850
- Sapphire Radeon HD 4650
- ATi 4630
- 8800 GT
- 8600 GT

Bookmarked two cards, they looked promising

I'm still new to all this and wanted some advice from more experienced people. Any suggestions and thoughts you have that would be helpful are appreciated! Thanks!
