OK. So until now I was seriously considering making my own PC with the Nvidia Geforce GTX 670 and an Intel Core i5 3570K. However with the recent release of Haswell and the 700 series. I am considering getting the newer versions. Upgrading will cost me over $150 extra (in Australia) and I am already over my budget. I want to know if it is seriously worth it and it will help if someone can understand that $1200 on a build is already quite a bit to me.
