Looking to do a first time build as was initially looking at getting the 4400+, however with the 4200+ out now and them looking to be about £80 cheaper than the 4400 I was wondering what performance increase the 1MB cache will have over the 512KB. I wont be playing games on the system (it'll be used for music and applications like photoshop/quark etc) so should I just go for the 4200?
