It's pretty crazy to think that a Graphics Card could have a large bandwidth, especially when it was released on 2009. But Radeon HD 5770 can be proof for such thing, and let's analyze more about this gpu.
Its gpu clock must be noticed as well, with 850 Mhz which is still fast even for today standard. All of them thanks to the DDR5 memory type which is always recommended to get for gamers instead of DDR3.
GTX 260 and Radeon HD 7750 is so close in terms of performance, and those cards are still reliable for 1080p resolution.
However you must bear with 1 gb size with Radeon HD 5770 thus it may not run maximally the games like Resident Evil 3 remake that needs at least 2 GB size.
Well with 3D Mark Firestrike it can reach 1,873 points and defeats GTX 550 ti and also Radeon Vega 3. However it fails to beat GT 740 and also GTX 650.
So let's try this product to play PUBG and with 720p low, it manages to exceed 30 fps. Plus CS GO can be played with proper on 1080p low and see the fps fluctuates from 20 to 40 fps.
From this product to best gpu for 100 dollars can make you play games with smooth, thus you need to try it.
