Questions about MSI GeForce GT 710

Yes

The prerequisite for this graphics card is a PCI Express x16 slot, then there is the question of the drivers for the operating system. No problem with Windows 7 or higher, there are also drivers for Vista 64 bit and for XP, and it runs perfectly with Windows 10 x64. The specified power consumption is 19W, which is relatively modest. I am very satisfied with this card, I do not have high demands, the price is reasonable and the system load is modest. I cannot judge whether the use of FSX will be better, I do not have FSX.

Since the card has HDMI 1.4, the maximum resolution is 4096x2160 @24 Hz.
