JUST BUY A MAC.
Haha JUST KIDDING not starting this fucking argument again.
If I was going to buy a PC I've always heard good things about ASUS. They seem to make pretty solid computers, lenovo doesn't seem too bad either. I wouldn't go with the acer though. I've just heard of some not so good things about them. No matter what though DON'T BUY an HP. Haha , their laptops are terrible just letting you know.
I found these that seem pretty decent:

Not as good of graphics card though on this one:

I definitely would go with the Lenovo out of the 2 you posted though I'm pretty sure.
