If your brother can wait 3 weeks to 1 month, I'd strongly recommend you go look at Toshiba's website, they always have good deals on their laptops! I bought one that I customized for just $400, their website always has deals & promotions on their hardware - I saved ~$250 on my laptop and I can get ~30fps in BF4. They are assembled somewhere in China, so that's why they take a while to ship (plus they had to assemble my preferred parts). I also recommend that (if you're inclined) to simply buy used RAM and install it into your bro's laptop yourself.
They probably charge $50 for something you can find used for $10.
I took out the slow 5200RPM HDD, and installed a 120GB SSD. I then removed their 4GB of RAM, and installed 8GB. I probably saved $300 doing these modifications myself. ...The only issue with the laptop was that it came with Windows 8 installed, and when I went to install Windows 7 I had to learn how to disable Win8 from being the preferred OS in the BIOS. It took me a few days to get everything working properly, but I didn't know what I was doing
