I just ordered an EVGA GTX 680 to replace my 570 and I was wondering if it would be worth it to buy the 3570k aswell? I know with my 2500k at 4.6Ghz my 570 does great vs stock core or even with turbo at 3.8 (may be wrong on turbo speed). I have a gigabyte Ga-z68ap-d3 witch has a pice 3.0 x16 and is IB ready and 8gb ddr3 with xmp1 @1600 and just wanna know if my current setup with the 680 will last for atleast a year or should I buy the IB while I have the money and go to liquid cooled for some future proofing? (I know future proofing is impossible)
