Hi Guys, I've had my MSI GTX 670 OC pretty much bog standard since August 2012, and its beginning to show its age a little, and I'd quite like to upgrade it. The rest of my system is all still pretty up there (4Ghz 3570k, 16Gbs o Ram etc). As always, I have an issue with spending more than about £220-250 on a GPU because I simply don't need anything better as I play many multiplier games at 1920x1200. Would my best bet be going for a 4Gb GTX 970? Or save money an get a second 670 for SLi? Or perhaps wait for next series of GPU's as I'm not exactly in a hurry.
