Mac Forums

Yes, the infamous question. I am going to college for graphic design, some people claim that mac's are wayyy better with photoshop than pcs. My mom thinks I should just buy a PC because it is cheaper and I am already used to the way they work. I have enough money to buy a 13" Macbook Pro, and have a few hundred to spend on college stuff. My mom thinks that if I just buy a 500 dollar PC, I'll still be fine. I would have a lot more to spend on school stuff, but I heard that PC's are laggy and slow when it comes to big files on photoshop. Gosh, I am so conflicted! Is it true that mac's are better for graphic design? I need some honest opinions people. I'm sick of the people in the mac store telling me I have to get a mac, and my mom telling me I have to get a pc. Someone just please help mee! Thanks guyss.
Oh and also, through my school I'm getting photoshop for only 99 dollars. So I'm not worried about having to pay for that too.
