Well, app games don't exactly take a lot to run or download, so you don't really need the 32GB, but if you have AT&T like I do and if you're going to download a lot of music or something, I think the extra $100 is worth in my opinion, I like getting the best when I buy stuff. When I talked to Nvidia, they said you can stream Steam games if you have a Nvidia GPU in your PC and play on your tablet, that's cool. Although I'm not sure why would anyone do that if you have the PC, lol. But for tablets, what you wanna look for is the things you want to use it for, such as if you wanna play games like you said, you want a fast processor and good image quality, that tablet has one of the best ones as of right now, so you're good on that. Size is also another thing, you don't wanna it to be too big like a huge table or too small like a phone, 8 inch is almost as perfect as 7 inches for perfect hand held. Also, you should look into battery life, you don't want it to die on it like every 4 hours, you'd want to get one that can last at least 8 hrs or higher. If you listen to music a lot, you should look into if it has great audio components. If you take a lot of pictures look for some high MP for the cameras that's installed on the tablet, but phones are probably better for it. Another thing tablets are great for is movies, I love watching movies on Netflix with my tablet, it's just a bigger screen than a phone if I don't have my PC with me, if you get the $400 one, you'll have 4G LTE and can use it online while outside the house, although I'm not sure if it's only AT&T. That's about all I can think of right now, but I hope it helped, I'll edit more if I can think of more, I haven't exactly been keeping up with the tablet world either, busy with my PC
