I have GTX 750 TI OC to 1.2Ghz.
HD 7850 is equal to my card but it has 256Bit.

What are disadvantages of 128bit.
I heard it lags in AA.

Please tell me settings which are not good for 128bit so i can turn off and play smoothly.
Would really helpful for others.

BTW i use FXAA

The only disadvantages of a shorter bus width (128bit and 256bit) is just less bandwidth being fed to your card. Unless you're doing a tri or quad sli/x-fire I wouldn't worry much about it. From just glancing at the two companies nvidia is a bit more optimized with their PCI lane usage than AMD is. It's mostly just numbers for advertising when it comes down to it.

128 bit cards are slow than 256 bit cards.The memory bandwidth of 256 cards are really great..AA drops down all the fps.And on 128 bit cards,playing with AA on is really impossible.But on 256 bit cards,you can play with AA on..That is why the 256 cards are priced more than 128 bit...If you have a good budget just get 256 bit card.You dont need to change your gpu too soon if you get a 256 bit card.In case if you get 128 bit card,i bet you definitely change your gpu in 1-1.5 year.So better get 256 bit.If you dont have enough budget to get it,wait till you get your budget by saving some money and then go on with 256 bit card.Select it as best answer if it helped you.,

The main benefit of a 256bits interface over a 128bits one running at the same frequency is the GPU has twice as much bandwidth to work with.

The main things affected by it is high resolution textures, high resolution displays and FSAA... stuff that can easily double the amount of bandwidth needed assuming the GPU has the processing power to match.

1366x768 and FXAA with High to Ultra preset is ok?
Or Ultra preset is not a good idea?

On that resolution I'm sure your card can handle anything you throw at it without a fit.
