Good trade?

I'm not but I also dont wanna get a bad laptop.

It's a better laptop than no laptop, and you probably won't get enough by selling the parts to buy one with those specs, especially since the 740 video card is pretty out-dated. If that laptop is good or not you will need to see when you test it, a lot of older laptops have issues with crashing during gaming, keys are work and don't work well, battery is bad, case is cracked, screen is scratched, etc..
