Hey guys, I have this EVGA GTX 680, (http://www.amazon.com/EVGA-GeForce-DisplayPort-Graphics-04G-P4-3687-KR/dp/B0083YF55U) and I found someone on Craigslist selling the same model except in the 2GB version. Is it safe to SLI these? Sorry if this question has already been asked.
Thanks in advance guys!
