This is my first time on the forum.
I'm going to build my own pc. I've choose i7 3930k and for gpu two GTX670 SLI. I want to be future proof so here are my questions.
1. What GTX 670 is good to run sli? (temps,cooling,fan noise) Asus DCii GTX 670 vs EVGA GTX 670 FTW ?
2. I heard that crysis 3 beta got 1.7GB of VRAM so is it worth to buy 4GB VRAM GPU'S ?
3. Is two 256bit cards in sli make 512bit ?
4. If I buy 2GB cards will it be future proof ? for next gen or maybe unreal engine 4 ?
​5. or should I wait few months for Nvidia 700 series ? (sorry I'm nvidia fanboy )
