Will the Sims 3 graphics run well with only an integrated graphics card?

I'm looking for a new, affordable laptop, but that proves to be difficult when nothing I find appears to be compatible with the sims 3 and all it's expansions and stuff packs. The main two laptops I'm looking into are these:

Lenovo with 1TB hard drive 6GB RAM -

Dell with 1TB hard drive and 8GB RAM -

But upon more research I've found that none have a good graphics card, just the integrated ones that I've heard aren t good for gaming, and I'm looking to play with higher graphics

But I've also heard that the integrated card draws off of RAM if there's enough of it (although that could just be my misinterpretation, I'm no expert) and I've also heard it should be running perfectly fine? I don't know, it's confusing.

Basically I need to know

1.) Whether either of those computers will run TS3 + expansions smoothly with decent graphics without any replacement parts like a graphic card, and if the RAM thing is true or not.

2.) If that doesn't work if there are other alternatives for that price that will run it by those standards.

No
