well for starters, youll probably want an i7 processor or better, an NVIDIA graphics card, and around a terabyte of harddrive space (1000 gigabytes for you if you dont know what a terabyte is) and probably between 6 and 10 gig of RAM. I currently use an ASUS Q550L, 13.5" (or close) touch screen, 1 terabyte of hard drive, 8 gig of ram, NVIDIA GEFORECE 745M graphics card, and an i7 processor, works really well for all my needs, there are some compatability issues between ASUS laptops and win 8.1, but they are minimal (for instance i cant turn off my track pad, and my keyboard doesnt light up anymore) but nothing that really interferes with general opperation of the computer, i find if im not playing dogfight my battery will last between 4 and 8 hrs on a full charge, with medium screen brightness and continuous use. the only real thing i dislike about my laptop, it heats up a lot when using graphics intensive games (dogfight brings it up to around 90 degrees, warthunder can get it in the range of almost 120) i have to use a small desk fan to suplement the internal fans, and tis heat seems to have damaged the keybaord in the past (might have been a defective keyboard, the new one hasnt shown any signs of malfunction yet, but the other one didnt for nearly a year)
ok....so i hope you understand my technical jargon, if not ask me to clarify...but id say look at best buy, theyve got some good products, and good waranty to go with it....had to replace my entire keyboard....didnt pay a dime. but definitly use google, and go to some places, my laptop is a little expensive, clocking in around $1200
