In the next 4 weeks I'm planing on getting a new graphics card and had originally chose the Gigabyte GTX 660 OC as it was a good bang for the dollar around $199-$209.

Now the new EVGA 750ti FTW and SC editions are out and I know it is a step below in performance when i checked my games with Game debate. Or should I just save up for a
Evga GTX 760 SC at $289.

My current rig is a gateway dx4850-45cu that I purchased from Future Shop 3 years ago.
Core i7-2600, 8GB DDR 3 RAM and a GT420 gpu.

I have purchased a Corsair CX 750m PSU and a new Enermax Coenus Black Mid Tower Window ATX Gaming Case for $44.99 to hold it all and been complementing a new MOBO and Processor LGA1150 or should I get a new MOBO LGA1155 and keep the i7 and get new brand name RAM?

Thanks for the help.
My budget depends on my tax return but last year was $800 CAD so between $400-800 CAD.
I Priced the R9 270x on newegg and the MSI Gaming 2GB was $299.99.
Gigabyte OC 2GB was $264.99
and the
MSI gaming GTX 760 2GB was $299.99
EVGA GTX 660 SC 2GB was $229.99

And is it worth investing in a haswell mobo and cpu?
My first thoughts were a Gigabyte Z87x-UD3H Mobo and a Core i5-4670k This would run me $429.98+taxes and freight.
Trying to keep to a black/Blue theme if possible. Was looking orginally at Asus Z87-A Mobo.
