Do you really have to buy high-end graphcis cards? Need help with this build...

What resolution will you be gaming at? At 1080p i think a 750 ti would be fine. The only thing with the 750 ti is you can't sli them. That 760 ti would do everything you need it to do at 1080p as well.

I think you'd be fine with a 750 ti honestly you might not be able to crank the AA settings to max but i think it would run just fine on a single monitor at 1080p. Going to a 760 probably won't give you too much of a noticeable increase unless you sli two of them. Going to a single 770 would net you the biggest gain. All in all i'd say it depends how much details you have to turn up on the game as it is quite demanding.

The difference is that the GTX 750 TI will require you to optimize your settings, while a GTX 760 or above will not.

You'll find that really the biggest reason people pay $500 for a video card instead of $150 isn't really because $500 is needed to max games, but rather because $500 lets them just hit the ultra preset and not worry about efficiency or anything specific.

People's definition of "ultra" changes. For example, in Metro Last Light, you can run it on "ultra" with 8xSSAA+AAA only on a GTX 780 TI or R9 290X. However, you can run it on "ultra" with 2xSSAA+AAA on a GTX 660, and "ultra" with just AAA on a GTX 650 TI. I put "ultra" in quotes because many people consider AA separate from the standard graphics options, since technically it never actually maxes and scales differently on different
resolutions. The difference in quality is very minor, especially considering to reach 8xSSAA you'll need to triple the price of the video card.

As another example, look at Skyrim. To run 4K texture mods, that requires a very strong GPU with a lot of VRAM. However, there's virtually no difference in quality at 1080p from 2K textures to 4K textures. So people who install 4K texture mods end up needing a GPU that costs twice as much just for a ~4% quality improvement.

I knew a guy on the Nexus once who forced driver HBAO+ and 8xSGSSAA in every game... Even when it didn't work correctly or the game already had AO and AA. Of course, it butchered his framerate so he spent his days online complaining about how his GTX 680 just wasn't strong enough. He even said you needed a GTX 780 to put Mass Effect 3 on ultra, which is simply ridiculous because I run it with all settings maxed at 100+ fps on my GTX 660. But he said it because he had basically broken his driver settings by trying to boost the game above ultra.

A lot of people do that; they run pointlessly specific effects in games and complain online when it doesn't work out like they want. There was another guy on the Nexus who ran a 4K Skyrim texture mod, but didn't use any anisotropic filtering. Every week practically he'd post updates on a silly 8k (8192x8192) texture mod he was making, because 4K still looked blurry. Eventually he decided you needed a card with 6GB of VRAM to get decent textures because of his apparently insane ignorance regarding anisotropic filtering.

That's the main benefit of getting a high-end video card; it allows people to jack everything up with no regard for actual noticeable quality or optimization.

So yes, a GTX 750 TI is probably fine for BF4... Possibly ultra, definitely high... As long as you're reasonably efficient and don't try to brute force unnoticeable or redundant effects in drivers or mods just for giggles.

If you want I could run some benchmarks with a 750 ti I have running in a backup pc at the moment. Best I could do though as I don't own battlefield 4. Have it running in a 945 black at the moment. If anyone knows any benchmarks that would be comparable to battlefield 4 I would gladly run them.
