Thanks rhy for your anwser, I was wondering that. How can a sucky video card run directx 11 and up and mine cant yet my old one is more powerful? And can only run directx 10 WTF!?! Ugh Lol.
Yeah, it's frustrating for sure.
Unfortunately those cheap entry level graphics cards tend to be really bad options for gaming. Both AMD and Nvidia often just rebadge much older designs with minimal tweaks.
The GPU at the heart of that GT 730, for example, was originally released in Jan 2011 as the 520M, an
entry level
laptop (!) gaming option. So although the naming scheme suggests the 730 is a "newer" card, it's really not.
That 4850 you have, though 2 and half years older again (released mid 2008), was once a potent desktop card, it has almost double the transistors of the GT 730, a better memory controller with faster graphics memory and has the power delivery and cooling to draw well over double the power. Though older, it's a better card.
Sorry again to be the bearer of bad news! You're not the first to get caught out by the labelling. Dot points like 2GB RAM and DX11 look great on paper, but sometimes they cover up a low end and outdated piece of hardware.
