So, i have loved Linux for years but have always been limited because of drivers etc, now i wanted to take the gpu passthrough approach in the past however its costly, but then i thought, would it be possible to run Linux via onboard graphics? Then run a VM with Windows using GPU pass through.
Would this not be wise? is there con in this?
If it is an Intel iGPU, then you should have no issues with a win 8 or 10 VM using OVMF. WIn7 VM and below probably would need a i915 vga arbiter patched kernel since they can’t use OVMF.
If it is an AMD iGPU, then I don’t know although you should be ok.
Theoretically yes, but Raven Ridge on Linux is currently sketchy at best.

It works fine, it costs nothing extra if you have an igpu, and like 35 bucks for a gt 710 if you don’t.
we have a wiki on this here:
Seems like we get a new thread almost every day with people having the same problems setting up a passthrough VM. The Purpose of this Wiki is to be a resource and reference for people who want to set up a VFIO system, or have one already and need advice or Tutorials for the various facets of that system.
I will be adding categories like ‘input’ ‘screens’ etc – these can be expanded as necessary.
Basic Setup
Guides on setting up a passthrough VM
The archwiki guide:
https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF
This is the gold standard in passthrough setup tutorials. It is by and large the most complete, best maintained, and most accurate reference available. The vast majority of the information is completely distro agnostic, with the single caveat being mkinipcio being distro specific (dracut on fedora etc)
This should always be your first reference.
Explainers/Benchmarks
Information on various ill documented or not-oft-explained aspects of VFIO. Benchmarks should also be put here as the effectiveness of many commonly suggested tweaks are not very well characterized.
Hardware buying and quirk guide: https://passthroughpo.st/vfio-increments/
Input
resources for people looking for keyboard/mouse input sharing solutions or other input-related topics.
Storage
Information on best practices for images, VirtIO, etc.
Display/GPU
VFIO Topics pertaining to your VM’s display, native or otherwise.
Audio
VM audio resources.
Distro Specific
Apparmor, distro specific software, issues, and workarounds.
Tools and Projects
Software that enhances the VFIO experience, or VFIO use cases outside of GPU passthrough

This is a tool that allows users to take advantage of KVMFR, using 3d accelerated VMs without needing a native display
