Well, when we look at it like this,
http://www.overclockers.co.uk/showproduct.php?prodid=GX-188-GW&groupid=701&catid=1914&subcat=1854
£120 for that 750Ti
http://www.overclockers.co.uk/showproduct.php?prodid=GX-328-SP&groupid=701&catid=56&subcat=1982
£144 for that 270X
You can clearly see that the 750Ti is the price performance king and you will save even more money, as it is far more efficient than the 270X. I always picture people who buy these cards as price aware and £24 saving is not to be sniffed at.
No it isn't. You do realise the GTX750TI is still a slower card,meaning it will have to be replaced quicker?? So over a few years you will be spending more in graphics card upfront.
KFA2 GTX660:

MSI R9 270:

Both around £130. R9 270 cards have been even lower for short periods.
The R9 270 and GTX660 against a GTX750TI which has been pushed to its limits?? Really now - so what happens when you overclock those?
Moreover,have you even run a midrange card??
My GTX660,H67 mini-ITX motherboard and a 80W TDP Xeon E3 1220(Core i5 2400) with an SSD and 2 HDDs consumes at most 200W during the combined test of 3DMark at the wall using an XFX PRO 450W PSU,which is Bronze rated.
My whole rig can run off a decent 300W PSU.
So if you had a Gold or Platinum rated PSU and an IB or Haswell based CPU,it would mean even yes.
That is peak power consumption. Usually it is around 150W to 180W at the wall.
Power consumption and PSU E-PEEN is only there to make people spend silly amounts on PSU you don't need.
PSU companies have made people gullible.
Anyone who is specced a rig on here will have at least a decent 300W+ PSU.
Moreover,I have run nothing but SFF mini-ITX and Shuttle SFF main rigs since late 2005.
You know the kind of rigs,where a 250W to 500W PSU are the most common??
I ran an unlocked 6800LE,ie,basically a 6800GT, off a 250W Shuttle TFX PSU with an overclocked XP 2800.
I ran a massively overclocked E4300,loads of RAM,multiple drives and an overclocked 8800GTS 512MB off a 400W Shuttle SFF PSUs on a blasted 975X chipset which drank power.
I ran a massively overclocked Q6600,loads of RAM,multiple drives and an overclocked HD5850 1GB at 950MHZ off a 450W Shuttle SFF PSUs on a blasted 975X chipset which drank power.
Plenty of people are running decent cards off 350W to 450W Silverstone PSUs.
The top end Valve SteamBox uses a Core i7 4770 and a Geforce Titan off a Silverstone 450W SFF PSU.
Those SFF PSUs are compact group regulated designs - they are decent for the size but not as good as full sized PSUs.
Thats just a few examples of what I have run in tiny boxes with limited cooling.
