You sound exactly like me. I went through this same situation about a month ago. If you just want a quick and easy answer, GET THE MACBOOK PRO! But if you want to know why, I will tell you.

Game Perfomance: The Macbook Pro runs games great! I can turn the settings up on most games and still get a great framerate. But do not expect to have all the settings turned up high on intensive games. You really have to shell out cash to do that. But in UT3 I have all the settings turned up. The only problem with the video card is that it doesn't like high anti-aliasing levels but that is ok. The pro should run all games just fine. The normal macbook i have no idea but my guess would be that it can't because the graphics card is that great.

Video card:I also like to play games on my computer. The reason I went with the macbook pro is because the video card is actually a real video card. What I mean is that it is made by a respectable company and it is meant to do some work. The macbook video card is just there to produce graphics so the computer will run. Basically it is the difference between a golf cart and an actual car.
Winner: Macbook Pro.

Processor: They can both have a 2.4 ghz dual core processor but the low end macbook pro has the same processor as the high end macbook. So the macbook pro wins.

The pro version is in all ways better than the normal macbook except maybe battery life. But this is ok because the pro has better hardware which draws a little bit more power. Since I have the macbook pro in which you want, I can tell you that in battery life mode, it gets great battery life. I have had it sit by my side for about 3-4 hours in battery life mode. It goes to sleep when not in use for 1 min but that is good.

The pro has a heat problem but that is easily fixed with smc FanControl. Just set the fan RPM to 6000 and it cools down quickly.

I know this answer is long and may not be well put together but I was in the exact same position as you and I want you to know that if you do not get the Macbook Pro, you made the wrong decision. Plus, the black version cost $200 more but is the same as the white one. From what you want the Pro is the only option for you. TRUST ME.

Oh and bootcamp runs great. I have Windows Vista Ultimate, I don't know why people hate it because i have had zero compatability issues so far.

So yeah, I was in the same position and my verdict is the Macbook Pro.

(Macs are way better than PCs. They are more reliable and you can run windows easily. So why get a PC when you can get a Mac that does them both? I hope you enjoy you new Mac. I know I do.)

Hope this helps,
