I will be building a new PC within the next month, and I'm trying to decide on a video card. The PC will be used for HD video editing and processing, with high-res photo editing as well. I would like this build to stay relevant for the next few years.

The cards I'm looking at are:

EVGA GTX 770 4gb Dual FTW ACX at 1.08 ghz (04G-P4-3776-KR) for $460

ASUS GTX 780 3gb Direct CU at 889 mhz (GTX780-DC2OC-3GD5) for $510

EVGA GTX 780 3gb Superclocked ACX at 967 mhz (03G-P4-2784-KR) for $550

EVGA 780 6gb Superclocked ACX at 967 mhz (06G-P4-3787-KR) for $580

The cost is a slight issue, but seeing as how the difference between the cheapest and most expensive card is only about $100, and the total build will be around $2700, it's not that big of a deal.

What I'm wondering is, what difference will a 6gb VRAM make when rendering large, processed HD videos? Also, the 770 card has a higher clock speed over all of the 780 cards, will this make positive difference over the 780 cards? And, does a card being "superclocked" mean it will run hotter, because I plan on using a Phanteks PH-TC14PE_BL 78.1 CFM CPU Cooler, rather than a liquid cooling system.

Thanks in advance for any advice.

When rendering large videos, I will go with the 780 6GB. But for gaming, I would go with a 3GB not 4GB as it will take time to process the image. Yes definitely a superclocked will run only slightly hotter than the same series which is not a superclocked version. The clock speed doesn't matter as much but the bandwidth does. A CPU cooler doesn't cool the GPU unless you get a GPU cooler.

Overall, the best is the 780 3GB by Asus in my opinion a superclocked isn't needed but if you can afford it then I wouldn't stop you. If you will be rendering a 6GB will last you a long time but not recommended for gaming in my opinion.

Lol... I didn't know the vRAM actually affected this stuff... Just get a 770 with 2gb or 780 with 3gb.

Get yourself 16gb of RAM instead or something...

I'm leaning towards the 6gb 780, but I will probably wait a few weeks to see what happens with the CPUs being released. And I plan on using 32gb of RAM, which will definitely help in Photoshop. I won't be doing any gaming on this PC.

Thank you for the help.

If you're not gaming on this PC, then just go with a 760 with 2gb or something... you don't need a 780 unless you're going for 3d rendering or something, and even then, the 2gb 760 will do just fine. There are system that work fine with those kind of programs using something much weaker than the 780.
