Hello. What are the pros and cons of 15" and 17" laptops, like battery life, components, heat, etc. Also, would you recommend Cyberpower as a choice for a gaming laptop? I looked at Alienware, but their systems aren't as customizable and cost WAY more.

CyberPowerPC are a decent brand IMO; they're one of the few makers I've seen that offer an i7-based laptop, although it's more like a desktop-replacement than an actual laptop!

Have a look at the Gateway FX series and ASUS and MSI gaming laptops for the best balance of price and performance. I especially like the ASUS W90Vp-X1.
