I'm buying a new GPU , sapphire radeon NITRO r9 390 and was wondering if my current motherboard will be able to run with it, gigabyte Intel z77 LGA1155? Will this MB last me a bit longer or am I better off replacing it? Will my cooler master HAF 912 mid tower case be big enough to fit the R9 390 also? I feel like I might have to replace my motherboard but I just spend 500$ on the GPU and new PSU. Hoping I can keep this one or if there is a good priced motherboard if mine doesn't work out.
Current specs:
Cooler Master HAF 912 Mid tower
Sapphire AMD radeon HD 6870 1gb
Intel core i5-3570k quad core
PNY optima 8GB
Gigabyte intel z77 LGA1155 AMD crossfireX
