No you will be fine. And with the performance of Haswell or the lack there of you will be just fine with the 3570K. The fact is the Haswell is not that far removed from what you already have and the only thing that is really upgraded is the igpu part and since you are using a discrete GPU that is not even a concern. Some have said only 5-10% increase others have said 10-15% in either case it is not enough to justify sidegrading to it from a already very good CPU.

Doesn't matter, I was just stating it wouldn,t bottleneck in the first place and you were going to overclock anyway so don,t worry about it.

Depends on the game. My stock 3570k held back my 7870 CF in Crysis 3 at 2560x1440 a little bit. My gpus were at about 90% usage when I had 100% usage on at least 1 cpu core. You're going to have to overclock the cpu a little to not have it hold you back. To everyone above, it absolutely will bottleneck (at stock clocks) 780 sli in certain games.

I would agree with you on that to. My point was only on the difference from the 3570K to Haswell. The performance increase from stock is not enough to even justify upgrading.

I will say that unless the OP is using a monitor with a resolution higher than 1080p or running mutlimonitors in a Surround setup i really think a SLI 780 is way overkill anyway. For the price compared to performance if he really wants SLI he would be better off with a SLI GTX 770 setup. Not near the cost and performance would still be very good. I run a SLI GTX 670 setup and even at 5760x1080 there is not a game I have that supports that resolution that I can not play on high/ultra with no problems. And that is on 2 Gigabyte GTX 670 2gb cards. Really the GTX 770 vers. GTX 780's are much like the GTX 670 vers. GTX 680 at the time. The GTX 770 cost alot less and has performance very close to the GTX 780 that it is not even worth it.

Since when does gtx 770 come close to a 780? It's not like 670 vs 680 considering they use the same chip. 780 uses gk110 same as the titan chip where the 770 uses gk106. Also if you overclock the 780 it ties the titan. Whereas overclocking a 770 wont yield the same results nor the gain that you would get from overclocking a 780.
