Two graphics cards vs one. 1gb each vs 2gb each?

Im planning on ordering a computer from cybertronpc.com (Any info regarding that site would be helpful but not a requirement to answer). The reason is because: 1) I dont trust myself enough to build a complete computer, i only trust myself to replace and add things to a computer that's already built and already works correctly before i start adding/replacing things. And 2) Because in some cases, after looking up all the individual prices and then seeing which would be cheaper: Buying all the parts individually and then building it myself or going to a website and picking a pc and then choosing the parts myself and let them build it and ship it to me, the price is either cheaper or around the same price. (Rarely happens but it's not THAT much more for my case)

I do not plan on Overclocking anything, Ima just put that out there right now because I want my parts to last as long as possible. I really wanna get 2 cards because I'll be mostly gaming, and having two cards eases up the work load vs just one if theyre the same card. The highest resolution ill be going is 1920x1080 and I also plan on recording my gameplay for certain games. Also, I really wanna be able to play the latest games and future games. And when i record gameplay, ill be recording it to an external hard drive to hopefully reduce or eliminate any lag that it might receive depending on the game and the games settings that are activated.

I dont plan on playing all the games with all the settings maxxed out just cuz i might be able to depending on the game and what parts i get. I do it smartly and only increase what really matters instead of maxxing whatever i can. But expect most of them to be in the high settings (though almost every game I'll have will be customized to my liking, but lets just say theyre in the high settings)

Would getting two 1gb video cards be better for 1080p gameplay and recording in 720p? (Does recording even matter with video cards or is that purely based on RAM? Which btw i plan on having 16 GB of RAM: 2 x 8 GB) Or is two 2 GB video cards better for 1080p gameplay. I want it as smooth as possible. I also know that some games do not support SLI / Crossfire very well, while others do. That's why I am thinking about getting two 2 GB video cards so that if i need to, i could just disable one and use the single video card to play that specific game that doesnt like video cards having a buddy to help them run the game. But I want your guys' opinions/facts.

And more specifically: If the processor was an AMD, which would you recommend based on these: - AMD FX 6100 3.30 ghz Six-Core
- AMD FX 4100 3.60 ghz Four-Core
- AMD FX 8120 3.10 ghz Eight-Core
- AMD FX 8320 3.50 ghz Eight-Core
- AMD FX 8150 3.60 ghz Eight-Core
- AMD FX 8350 4.00 ghz Eight-Core

And then which video cards would you think/know would match up perfectly with them? (2 of them)
- Radeon HD7750 1GB
- Radeon HD7790 1GB
- Radeon HD7850 2GB
- Radeon HD7870 2GB

Lastly, if i were to get a processor that's going the Intel route and not the AMD route, what video cards would pair up very nicely with an i5 4670 3.40ghz quad-core or anything that's i5 4th gen series? (Again, i will not be Overclocking anything). Anything that's at least a GTX650 Ti or higher would be ideal because it'll be for the latest games out now and for future games that i'll still be playing at 1920x1080 and record in 720p. Oh yeah, money isnt a HUGE concern for me, but it'll be nice to know what you guys think/know is the best bang for my buck that'll match up nicely with what i listed above for the processors (Not getting a Titan, too much money atm)
 
For me the choice would be the Intel i5-4670k and I know you said you won't be overclocking but the difference between the K model and non-K model is so little that it only makes sense to get the K model. The resale value of the computer will be much better with it.
To go with the i5-4670k I would get two GTX 760s, Asus just released a video card with dual GPUs and they were the 760 GPUs and the card benches as good as the GTX Titan. So by getting two GTX 760s you will have great performance in games. The GTX 760 comes in either 2gb or 4gb models and the 2gb model will work fine for your needs.
