I am trying out on my laptop first because its a hd 5730. I downloaded latest drivers but the gui miner says I need the SDK drivers. on this site it doesn't list that its compatible with win 7 or my card. is it possible to min with my card on win 7?

DO NOT mine on your laptop unless you purposefully want to kill it.  I have a laptop with a 5730 too and I have never bothered to even try it.  A cheap 5830 or 6870 will set you back $100 or less and will mine 5x as fast.  If you kill the display in your laptop that laptop will be worth $20 for parts.

I really don't understand how BTC mining works.  Why is GPU power so much more important than CPU/RAM power?  I have an i7 Quad-core 3.09GHz with 24GB DDR3, but I'm not a big gamer, so I just put an EVGA 1GB GTX 460 in it.  I didn't even know what a bitcoin was 3 weeks ago, so I'm still just screwing around, but you're telling me that if I just put an $800 video card in my rig, I can make my own?



The calculation to mine BTC blocks and process transactions, SHA-2 works very well multithreaded and parallelizes readily. This means hardware with a lot of cores like an AMD GPU can excel at it. Nvidia GPUs with less cores that each have a higher degree of sophistication such that they keep up in graphics processing lag behind AMD GPUS, because more cores and more threading helps more than the increased sophistication of the Nvidia cores. The i7 with its core count and being near the peak of sophistication doesn't stand a chance.

Or as someone one metaphored: NVidia cards are like having 4 MIT grads doing your all your math homework. Yeah, they can do pretty much anything you throw at them, but there's only 4 of them and they can only do so much in a given time.   AMD/ATI cards are like having 1000 high school grad honors math students doing your homework. THey might not be able to do the most advanced trig or calculus problems, but they can do hundreds of times more basic functions in a given time period than the 4 MIT guys.

or something like that.
