from the home page click on the computers & tablets department and chose all laptops. on the left of the screen are a bunch of categories you can filter like price, brand, screen type/size and such. start checking boxes for what you want. i checked i7 for cpu type, 8gb for ram, dedicated for gpu type and a few others that matched what you asked for.
playing with these filters is a great way to narrow things down some. you can adjust one criteria to see what it does to the price such as change i7 to i5 or dedicated gpu to integrated.
you can do this type of filtering with most everything on newegg. i use it even if i may not buy there just to help figure out a model i may want. for instance if you find a certain hp laptop fits what you want, you can go to hp.com and look that one up there. sometimes you can custom configure it even more and take advantage of freebies offered by the maker. my last laptop got a free hd screen, blueray drive and double ram free from hp that was not available on newegg. only added like $25 to the price
