Thank you, looking now.
Yeah I got that part, you were very clear , it was me that was thinking about of a crossfire setup with the A10-7700K an a R7 250.
An me that thought a Newer AMD card would make best use of PCIe3, which I was wrong about.
I was only thinking about 16GB of RAM for the A10, sorry I didn't make it clear.
Cheers for all of that, gives me loads to think about, very many thanks.
