I'm between the Gigabyte NVIDIA GT 640 1GB DDR5 or the EVGA NVIDIA GTX 750 2GB SC, clearly the 750 is better, but my processor is an Intel Core 2 Duo E6700 (2.66 GHz), so I don't want to waste my money in a card that I won't use fully (750) due to bottleneck problems, Which of them should I buy? (Or if you have any other suggestion, I'm searching for 60W approximately power consuming cards, I can't upgrade my processor is the best one that my MoBo admits :/)
 
Solution
The 750 maxwell architecture was designed to take pressure off of the CPU and lend it to the GPU. The 640 would save you a very small amount of money and woll become obsolete before the 750. Get the 750 it also ain't bad with medium setting games ;)

Get the 750. My friend has an E8400 paired with a gpu around the same power as the 750. Expect your CPU to bottleneck in more cpu intensive game such as planetside, or other games with a lot of units on screen

Also, I would recommend buying the AMD equivalent to the 750 (the r7 265) because of a new technology from AMD called "mantle" which will help to reduce your CPU bottleneck in games such as battlefield 4

I agree with you on saying to get a GTX 750 but not much point in mantle unless you got a nice powerful card to run it on.

Mantle only works with certain games, plus it consumes A LOT of energy, unlike the 750 that only consumes 55W. I searched what SycoSight said and it is true, Maxwell works very independly from the CPU, so that means lots of bottlenecking problems solved! Thank you everybody!
