New Build? Titanfall? R9 280x or R9 290 or GTX 760 or GTX770

[pm7769]

I just made a new build with the following specs:

i5-4670k (OC'd to 4.6GHz)
Asus Maximus VI Gene
Corsair RM650
Kingston HyperX Blu 8GB
Seagate 1TB 7200rpm HD
Corsair H100i cooling
AMD HD7850 2GB GPU

I'm considering some upgrades in the following order: GPU, RAM then SSD... is this the correct order?

I'm bent on upgrading the GPU because while I get 60fps with V-Sync on on a 1366x760 display, I couldn't do Insane texture filtering. I got Anistropic 16X and 8XMSAA I'd really like to be able to and Titanfall is the only game I intend to play with this build.

I want the most optimized GPU with the most value and some room for future proofing. I know GTX780 would be too much; I reckon my build would last around 4 years and the GPU I want to last for around 2-3.

I'm bent on the NVIDIA cards because they're partnered with Respawn, but problem is I only get 2GB of VRAM from ASUS (I'm trying to make an Asus build) for the GTX760 and GTX770 so I'm looking at R9 280x or R9 290 which have 3GB or 4GB VRAM.

But then now I don't really know... so if you could give me some ideas, I'd really appreciate it. As for budget, it's a really wide range. I'd go to around $500 I guess, but I hope not to spend all of it if I don't have to. Titanfall's really light in my opinion.

I would stay with your 7850 if you plan to stay at that resolution.
You can always see how the 7850 does with Titanfall before considering an upgrade.
