A:AnswerWell the memory bus is full 256 bit vs 64bit and 192 bit. compared to newer 6400 and 6500XT.I place the card in pcie 4.0 slot. I have had no issues and works very well. Asus
TUF GAMING B550-PLUS motherboard.
A:AnswerIf you have the standard 180w power supply provided with the desktop, then no. This GPU uses 185w alone. I would recommend upgrading the psu to a 750w if possible. I would also recommend a "Low-Profile" video card. it'll be smaller, but should fit in any sort of case. Some gpu's have a bracket you can change out for Low Profile. For the specs of the desktop, I would say keep using the 730, I have one in my old pc and it's still working.
A:AnswerOn paper, yes. You have the expansion slot for it. But the recommended power supply is 550W. I think your system
has a 500W PSU. The RX 580 has a max 185W TDP. Take into account other component power draw. If it is just for regular use and not for heavy gaming you might be okay, I don't know the dimension of your PC case . The card is about 10-11 inches in length. There might not be enough space for it. I hope this is not a recent purchase (Desktop PC). It is not upgradable to windows 11, not if you want support or security patches. You have about 2 1/2 more years for windows. 8th generation and up intel cpu is needed.
A:AnswerIts a big video card or as I call it a big video board. If you have a full size ATX tower it should fit. But a mid size or micro ATX might not fit.
