Advice Request: Projector

Hey I am looking to get my first projector and would like some advice on what i should be looking for.

Some details:
Price: $1200 - $1600
Throw: 10-13 feet
Screen size: Been looking at screens, 130 inch seems about right, I have a large wall to work with.
Other: I don't care about 3d, I am not against 3d just not something I care about.
I don't really know what else, I don't have too many concerns, I just want the best picture for my buck.
I need to be able to have the projector off center from the screen, not sure if this is an issue, or possible, if not I can make it work centered.
Also I really like Frame Interpolation, I would be willing to spend more for a projector that does this.
I do plan to game on it, but not the main use, but something to consider.

I've been looking and doing some research and the few projectors I've noticed that seem about right are:
Epson PowerLite Home Cinema 8350
BenQ W1070

The Epson is two years old now and it seems to me there should be better upgrades for it by now? Or are there but just at a higher price point? The BenQ has 3d which I don't really care about and I am worried if I bought that I would just be spending extra for a feature I don't care about.

Screen tips would be appreciated also, been looking at the Elite screens on amazon:

I have no idea what the difference is between the different versions are but I do want to go with the largest I can for about $300-$450.


Thanks in advance for any and all advice!

Yeah I've been reading a lot of reviews and I honestly feel I might drop the extra money for the Epson Home Cinema 5020. Although I don't care for the 3d, the split screen option sounds awesome, along with the frame interpolation. Just not quite sure I want to drop that much extra money...

Ok I think I have a better understanding of what exactly I am looking for, I will update the first post with this also.

From most important to least important:
Frame Interpolation
Picture quality (crispness, deep blacks)
Good for gaming
Slight ambient lights (mostly light from a computer monitor)
Split screen
3d

The Epson 5020 seems to cover everything but seems to be lacking the ability to game on it alright. If there was an option with everything but 3d and split screen that would be perfect.

Looking into the BenQ W7000 now, has the frame interpolation, 3d, split screen and interpolation with 3d.
