My old computer broke (Because I was being stupid) and I got a new one so I could continue to play Bioshock. Unfortunatly, when I start the game, the minute i'm in the water, everthing is black except for the bubble, which are now white squares, and the fires. I've re-installed the game with the same results. Afther looking over my new computers hardware, I found something. Sure, my CPU can handle the game, but the Video card can't. My current card, a ATI Radeon Graphics Processor (0x791F), has a pixel shader and vertex sharder of only 2, instead of the games required 3. So I need help finding a better grafics card, I don't know which ones are compatible with my current computer.

Here are the current Vid Card specs:

ATI Radeon Graphics Processor (0x791F) Is there software could download to update my shaders to version 3?? Or do I need a new Grapfics card?? Prices right now don't matter, and I will be grateful for any help.
 * Video RAM= 894.0 MB
 * Hardware T@L
 * Pixel Shader version= 2
 * Vertex shader version= 2
 * Also, it's a laptop computer

Thank you.
