Currently I have a MSI GTX 760 Twin Frozr. My CPU is an i7-950, which I will be upgrading to a 4770k or possibly the new proccessors but no clue yet. Either way it will be a 4770k or higher. I am thinking if I should get another GTX 760 to run SLI. I hear the performance is good and I have the 2gb edition. I hear that having the 4gb version wouldn't make sense because of how the GTX 760 utilizes its vram. I also only game in 1080p with one monitor. So is it worth getting another GFX card for SLI?
