Quick Q's

[Tee ay eye]

People should help me make decisions on certain things because I am not explicitly educated on computer hardware (just basics)

Errr, I can tell that some of them are obviously better than others, but I'd appreciate it if whoever answered could explain to what extent A is better than B (especially in processors)

I'm getting a laptop, so I can't exactly pick and choose, and these are featured in some of them.

Here's a list of the laptops I'm looking at, actually (it would be pretty cool if you guys just checked the computers out and shared your opinions)

The new Intel core i3's have a built in GPU that's actually on-die and has dedicated memory. Built in GPU's have been historically terrible for any kind of gaming. But the net "i series" from Intel is definitely different.

If you're really looking to do some serious gaming, then you'll want to have a discrete video card. But if you just want to do some video editing (I'm sure you do, Tai) streaming HD video to a TV, and stuff like that, then the Intel core will be sufficient.

EDIT: To give you an idea, my laptop has an Intel i5, and no discrete video card. I can play Starcraft2 on low, and stream 1080p video to a TV without any problems. Haven't done video editing yet, but I bet it'd handle it.

Your laptop here...

...is the only one you listed with a discrete video card. It looks like it'll have the most power of the machines you listed. But, of course, it's a refurbished laptop. So you have the risks involved with that. I'd make sure it has a good warranty before you buy it. But otherwise it looks like it's the best buy.

EDIT2: "Discrete video card" just means that it has an actual video card installed. Like one from ATI or NVidia, generally. Usually PCI-e. The alternative is a built-in GPU, which aren't as good. (But significantly cheaper)
