GPU Update help

[Deepak8822]

I am planning to buy either one of these cards
Nvidia GTX 750 TI 2gb DDR5 OC

or

Nvidia GTX 660 2gb ddr5 192 bit

which will be best to buy?
gtx 750 ti is newest version and 660 is old but 660 is fastest card.
So I am confused which one to buy..
Please help me to choose.

Config:
Intel I5 2310 2.90ghz Processor with DH61WW Board
12 GB GSkill DDR3 Ram
1TB Seagate HDD
Amd Sapphire 6770 HD 1gb ddr5 graphics card

If you are gaming, I would definitely recommend the GTX 660. If you want to save some electricity, go for the 750 Ti

Of course get the 660. It's more powerful than 750ti
