Hello guys, I get paid every month from work like you do usually but I won't have enough to get all of the new components. I already bought a case and put my old components in there.
I am tempted to buy the mis 970 next month and put it on my old motherboard and basically I want to upgrade everything (I already upgraded the CPU swell).

Two questions, I know the GPU will run more efficiently on my newer motherboard as its more up to date, but by how much difference? (I have a asus m5a78l-mlx from guessing)

2nd question, I think it would be better to wait an build it all at once but I seriously can't wait for 3 -4 months of just components waiting in my house doing nothing and waiting until I got everything. What do you think?
