Well the rig's been built and it's all working properly as it should. thanks for all the input guys. it's been a real help. Although I would've saved money by waiting for the GT I think my computers great and I cant complain about it! Only thing is that my 22" monitor reverts to using it's standard speakers in TV mode, I'd like to change it to my PC speakers but without having to physically change the jacks. I'll have to take a look around I guess.
Great PC, Great monitor! Lovely picture quality, and very very silent!
