yes there are and there can be
The Radon HD 5450 is a graphics card series from AMD designed for entry-level users who need basic graphical performance for tasks like HD video playback or light gaming. It's not suitable for demanding gaming or graphic-intensive applications due to its limited performance capabilities compared to newer graphics cards on the market.
The GeForce GTX 580 is either the best or the 2nd best graphics card
Depends on the Graphics card with the PC
The computer has a graphic by the graphic card, (video card) the better one you have the better graphics you have. HD 3550 is better than HD 750. So more the number on the graphics card the better yours is. Or it might be in the option and turn up the graphics. It might lag if you have a ok one, but turn down if it starts to lag. And eventually you can find one that suits your graphics card.
They're both horrible laptop gaming chips but the x700 will give you better performance.
