My PCIe GT 440 does an E@H WU in 90 minutes. I originally planned to buy the GT 520 but after I read some reviews and saw the performance being so bad, I went for the GT 440. Some reviews said the GT 520 is so bad, it shouldn't even exist :)

GT 440 = 311 GFlops / 65 W = 4.78 GFlops/W
GT 520 = 155 GFlops / 29 W = 5.34 GFlops/W

When you have a low power consumption requirement, GT 520 is better than GT 440. I don't need a very good performance, just want to run some WU's without heating my computer.

Right, and I went for the card which gave me most performance for my small budget. You'd be surprised how cool the ASUS GT 440 runs even under full load. It never goes above 60°C :) But like i said, I went for performance within my budget

Ok, but it isn't so cool, it's dissipating 65W inside your computer and heating the HD, mobo, etc. So you need a better fan to keep a low temperature inside. And this extra heat goes to the ambient air...

An E@H WU takes 159 min. in GT520, against 90 min. in GT 440, so:
GT 520 = 159 min x 29 W = 77 Watt-hours (1 WU)
GT 440 = 90 min x 65 W = 97 Watt-hours (1 WU)

Here in Brazil the summer is very hot, and I don't like air conditioning systems. Better power efficiency is an imperative requirement. Fortunately, you don't have this problem.

Speaking of GT 440 - I like

Speaking of GT 440 - I like the little GT 440. Mine does a BPR4 unit in 64 minutes. I'm quite impressed how well it works - old GTX 285 with at least triple the power consumption is only twice as fast.
Poor thing never saw 3D or any graphics apart from text console, though... :)

Actually, it isn't heating up much as one side of my case is always open. My drive is actually hotter than my GT 440, when I touch both of them to compare and my drive is placed fairly above my GPU so it's not the GPU that's heating it up (I think it's the CPU with the big ass heatsink from Scythe) :)

And as I mentioned, I bought it for performance within my budget. I'm not trying to dispute that the GT 520 uses less power (we all know it does) but it also has terrible performance. But you went for power efficiency, not like me for performance within a certain budget :)

I'm actually thinking of buying the GT 520 for my workstation. Since I don't play games but am an avid movie watcher, and the GT 520 is more than enough for hardware acceleration of films (VDPAU), I think it'll be a nice fit for my workstation. Power efficient, cheap and quiet (saw an ASUS GT 520 with passive cooling)
