The Asus is definitely the best bang for the buck in terms of cooling and quietness. Their GTX cards consistently outperform the same models from other brands when it comes to benchmarks.
Also, THERE IS NO REASON TO BUY A GPU WITH 4 GB OF MEMORY. No games will make use of more than 2 GB. Save your money.
OmarFWI personally do need more than 2GB. I do 3D rendering and the CUDA just fills up when rendering high resolution things, especially simulations. As for video games, you are totally correct.
OmarFWThere absolutely is actually. I play at 2560x1440, and at that resolution, pretty much every AAA title greatly benefits from more than 2GB VRAM. Also, I do a lot of GPU-accelerated tasks like rendering and editing, which also greatly benefit from more VRAM. Gettin a card with mire VRAM can be extrememly benefitial for future-proofing as well. Both Xbone and PS4 have much more VRAM as well, which means it's extremey likely that ports to pc will be more optimized to use VRAM.
OmarFWIf you plan on keeping a card for a while, more than 2GB is a good idea. Games right now are rapidly approaching that barrier and a ton of games use up >2GB when at resolutions above 1080p.
