Summary: is it possible to get a cheap motherboard that supports an AMD CPU, 2 Nvidia GPUs and AHCI for SSDs?
UPDATE: Turns out the SSD works with the old setup (thanks, @Journeyman). I now have the SSD along with the newer Nvidia on my system. I have a spare Nvidia 560 Ti.
I built a PC 5 years ago with an AMD Phenom II X6 1100T CPU.
I bought an SSD recently but realized that it has problems due to lack of AHCI support on my motherboard.
I had an Nvidia 560Ti but recently upgraded to an Nvidia GTX750.
I'm planning to buy a new budget motherboard. I want one that supports SSD/AHCI, but since I have 2 Nvidia GPUs, I was wondering if it is worth getting a motherboard that supports multiple GPUs.
