I currently have a GTX 670 FTW 2GB video card. I am wondering if I should run SLI or wait for the GTX 700 series. My main concern for the longest time was Crysis 3. I'm honestly past the fact that I won't be able to run on optimal settings. Or so I was told... Now, my concern is Battlefield 4. Though we do no know the system requirements of BF4, we can assume they are going to make it a demanding title. With that being said, and from what PC gaming hardware history shows, can I assume GTX 670 SLI will run it fine or should I wait for the 700 series? Thanks in advance!
