Need help with upgrading GPU, monitor, and memory.
So I have a newish motherboard (about a year) it's msi with an i7 4770k. I have old memory that shouldn't be in there really. It's like 2 different kinds that aren't the same speeds or types. So I need help with memory. I also have an asus gtx 670 that i'd like to upgrade from. And i'd like a monitor but I don't know if a new gtx 970 would be able to take advantage of a 144 hz monitor. Any help with any of this would be greatly appreciated. I'd like to order the monitor tonight since it's really good deals going on.
EDIT: I'd also like to add that I'm wondering if a 970 is an upgrade from my asus gtx 670
