Its a headache choosing when you guys put forward the pros and cons.
It would have been much simpler if i could push my budget to a 670 or would it?
Thanks
What are you going to gain with a GTX 670?
Don't get me wrong, the GTX 670 is probably nVidia's best card of this generation - BUT it will cost over £300 for a custom cooled version.

At this point as imiginy has already pointed out you would probably be best off with a GTX 680 on 'sale'
As for the GTX 660 vs the GTX 660Ti, the GTX 660 is indeed a bargain, but the GTX 660TI offers a boost, where you will notice it.
The GTX 660 may give 45fps for example, a GTX 660TI will give maybe 52fps. source: http://www.bit-tech.net/hardware/graphics/2012/12/10/zotac-geforce-gtx-660-ti-2gb-amp-extreme-r/1
This will be noticeable in games.
The obvious choice would be ATi, but the GTX 660 Ti is an excellent card at 1080p, I do agree however that it would be better if it was cheaper.
This one make most sense:

But as Rusty has said, you may experience coil whine and fan noise with that reference design.
