What are the best gpu - pci exp16 1.1? (main speed + version of directx / shaders + video memory)
It looks like I have the first generation pci exp x16 1.1?
and I stuck nv210 vidyuhi - there is the second
generation
.
maybe the channel is slow and for example nv670 will be idle
or there will not be enough corny power?
at least once in 4 speed vidyuhu pick up and 2-3GB of video memory.
Compare by power consumption first?

Answer 1

I will say so. platform 2007. there just the first version of PCIe.
all modern AMD RX580, Vega, GeForce 1060-1080ti class cards work fine. Everything depends on the CPU of course.
therefore, a question without specifying the platform, processor, memory cannot have a clear answer.
Even the purpose of the PC is not disclosed.
