Currently I have a GTX 770 4GB.

Current build is a

i5-4690k processor,
8gb of RAM,
1 4GB GTX 770
750W PSU
Mid Tower Case
1TB HDD.

(No SSD at all, is that bad?)

First of all, if I wanted to get better GFX performance, would it be best to upgrade the card to a 970 or buy another 4GB 770 and SLI them?

I may also get a full tower case to have more fans and cool everything better. (Currently the highest temp under load for the GPU is around 80C.)

Thanks guys.
