As far as I'm aware the purchase price is fixed. However, if you were to amend your order and remove the GPU then add it again, that might work. Not sure where you would be in the queue though!
There is. Right at the bottom of the list - "NONE, I ALREADY HAVE A GRAPHICS CARD" but then you wouldn't get the graphics card at a later date so you would need to source your own.
Good luck with that.:LOL:
I talk to loads of people and not 1 mentioned they had a TUF or MSI. Then again I never asked and most of them aren't gamers lol. Keep calm and carry on...
