The EU EVGA site sells the 460 FTW at £170 and the 460 FTW EE at £175.
As far as I understand it from previously having a 460 SC EE, they tend to be slightly noisier as it is having to push all the hot air out the EE, not that the 460 was a loud card. I would go with the regular 460 ftw, but if you don't have a well ventilated case I'd go for the EE version, as performance wise I honestly don't think you'll see a difference as it's the same cherry picked gpu on either card.
But I don't understand why your looking at spending £170 - £200 on a 460 mate? you should be looking at a 384 core gtx 560, and if it's EVGA you want I'd go for
560Ti DS Superclocked for £190, it's a better performer.
