So I just bought an AIO desktop not too long ago. It's a Gateway ZX4931, and it has been working great. It's got a great processor for me but the ram isn't very good, I am planning on upgrading it later. But I was wondering if there was a way that I could install a new graphics card. It only has 64mb of dedicated vram. And it's not very good when I want to play games. I have a laptop with 512mb of vram but I like the faster processor and bigger resolution of my desktop. So can I buy some small graphics card that may fit in my computer? I think some should fit. It can fit the stock fan for my cpu in there so I think it might fit a graphics card by height. Where could I find a compatible gpu? And would I have to buy a new psu too? Thank you for the help in advance.
