Okay guys i'm new to the whole Mac scene so need some advice Im looking to buy either the i5 or i7 with 2tb and 4gb ram but can't decide if the i7 is worth the extra £160. I'm going to try my luck at gaming using bootcamp, other than that its the usually web/movies etc.... Looking at the various sources the GPU looks like a bottleneck but Im think more in terms of like in a years time when more games might use extra cores and multithreading.... is the £160 really worth the future proofing.. Also is there any extra heat and noise? due to hyper threading? Alternatively should i hold out a few months as Im sure there must be a refresh in a few months with Lion coming?
