I thought so, it only has 1536 mb.
It's not about VRAM, it's about the graphics card's overall power. Even a card with 1.5GB VRAM would run the game good with a ton of crap on it if the GPU itself is strong enough (that stands for Graphics Processing Unit, just to clarify since a lot of people like to supplement the term graphics card with GPU). If you want top-notch graphics, you need top-notch hardware, period.
this is good enough though?
Yeah, 780 is good enough and i7 4770 is a pretty damn good CPU. Do note that even those components would have issues with badly optimized ENBs that have a metric crap-ton of dirty code in them, so real-world performance with specific ENBs varies.
On the other hand, the build itself is a plastic piece of overpriced crap, even my HTPC weighs more than that. But I guess it'll work right as long as it has a decent airflow (but they don't want to show it's insides). Do look for reviews on that specific machine, I have a bad feeling just looking at it.
