i5 4670k and gtx 650Ti

[Muchobanana]

I am currently in the middle of deciding how to build my first pc for gaming. I would like some input on what i have put together and what i plan to do in the future.

Current future rig setup:
CPU: i5-4670k 3.4GHZ
MOBO: Asus Z87-A
RAM: Vengeance 8gb (1x8gb)
GPU: GTX 650 Ti 1024MB
PSU: Corsair CX750 Builder
HDD: WD Blue 1TB
CASE: Antec Three Hundred

Now i know the GPU is a little weak for this setup, but my plan was to get another 650 Ti and SLI them in the near future as well as add another 8GB of ram. I was wondering how this plan sounded to you guys, any help would be greatly appreciated.

UPDATE:

Ok so i made a few tweaks. I decided upon the i7 4770k, vengeance 2x4gb and a gtx 760. How does all that sound now? I am a little worried the 760 won't fit in the mid atx case, what do you guys think?

650 Ti (Boost even) in SLI are weak in comparison to newer generation cards, they were good in it's generation, but I would recommend getting a GTX 770.

I would just do 2x4gb from the start, you don't need to get more RAM than that. and for the video cards, what enemy said.
