The fan on the MSI is identical to the one on the EVGA. Backplates are useless on 460s as they simply don't get hot enough.
And the 460 is not faeces and never was, it will end in the hall of fame for singlehandedly turning Nvidia's fortunes around.
As for not knowing how to overclock a GPU? there's never been anything simpler. Firstly what you do is find out what the EVGA is clocked at, like this -
Core clock - 850mhz
Shader clock - 1700mhz
Then you look at the MSI -
Core Clock - 725MHz
Shader Clock - 1450MHz
Then you download MSI Afterburner (infact no, you install it from the disc MSI give you).
And you unlink the shader and slide the wee slider to the right until the clocks match.
Three areas. 1. the "link" thing. Unlink it so they slide independantly. 2. The core speed. 3. The shader speed.
Your memory doesn't really need touching. Bingo bongo same clocks, same speeds, £30 in your pocket.
what about this card i could get compaird to that 460
EVGA GeForce GTX 560 1024MB GDDR5 PCI-Express Graphics Card
(Aria GPU)
plus i get 3dmarck 11 free with it
The non Ti is a heavily down trodden 560, but the 460 is better and, £40 cheaper. Just because you have the money it doesn't mean you need to spend it all mate. Sadly the GTX 470 Amp ! cards Ebuyer had for £153 are now all gone, because they would have been a serious step up
