Stay with R6970 Lightning or upgrade to GTX 660 TI?

[solinvictus01]

With the release of the GTX 660 TI and all the positive reviews it's been receiving I'm tempted to upgrade from my current GPU configuration (MSI R6970 Lightining) to the GTX 660 TI. However, I've started to think that I may not notice that big a difference between the two cards.

What does the community here think? Should I upgrade? Or should I stay with what I have?

Here's my build:

2500K at 4.2 Ghz
12GB 1600Mhz RAM
27" 1080p display.

Thanks!

a HD 7950 would be a better upgrade than a GTX 660 ti especially if you like AA
