I have a gtx 680 and a 550w psu (and some random case) and I have $200 nzd ($130 usd) to get a cpu that wont bottleneck the 680 (or not bottleneck by much) and a motherboard (no ddr2 that is hella expensive for ram I might aswell go with a ddr3 board as I would save $10), 8GB (the lowest I am willing to go is 6GB) of RAM and HDD of at least 500gb to go with it(mainly used parts). I was thinking of a i5 2500 or 2400 which would cost me about $100 but then I have $100 to find a motherboard ram and hard drive which surprise surprise the lga 1155 board would cost me $80 or more if used and $20 to find a HDD and some RAM is impossible (that is of decent size). So can someone recommend me some ideas on what to look for used or new and if anyone from NZ can give me some good sites to find used or really cheap parts. Thanks
