Default 570 sli?

I have a GTX 570 classified running along with an i5, but i want some more performance. So would getting an extra 570 and running them in sli, result in a major bottleneck because i'm not running an i7?
Also, will a 750W PSU be enough? (Chieftec nitro 80+ bronze)
This is going to be used for gaming, but the 570's won't be OC'd, and the i5 about 3,5-3,8GHz

I don't think so. As far as I know the i7 won't provide any extra power for gaming as no games require more then 4 cores at the moment. Now if you are doing something else like video or graphic I have no clue at all.

It also might depend on which i5 chip? Let the experts know what your computer usages are and they will be able to give you a better answer.

Your good to go with a 2500k. 2600k makes next to no difference in games.

One of the PSU guru's here should answer that one = I think you would be very close on a 750 watt.

Questions to give the Guru's information:
What brand/model of PSU is it?
What kind of overclock are you planning for the 2500K and the 2 GTX570's?
What else do you have in your PC? How many hard drives? Water cooling? How many fans? Anything else?
What do you want to use it for? Gaming? Folding?

MIght be a bit tight, but you should be just within the margin I believe.
I have twin SC 460's on a 650 with an I7 so given that you should be aboe to do it.

Not knowing what psu it is, i'd say 750 would be pushing it.
