I was wondering if I could grab some advice. I have one EVGA Classified GTX 570 and I'm looking to grab a second. However I'm aware these cards can get quite hot in SLI and I have some concerns.
The board I have (P8Z68 v-pro) has the 2 primary PCI-E slots right next to each other. A third slot at x4 speed is further away. Would the performance drop off be huge if I put the second card in the x4 slot to save heat, or will the heat be not as badas I'm thinking and I should put it in the higher speed slot?
I have an Antec 902 case (2x large fans at the front, 1x fan on the back and a beefy one on the roof - no fan in the window panel as yet).
Any advice or insight you could provide would be much appreciated.
I think you should be fine, But I would add a side fan too. Using the PCI-E x4 slot will hurt your performance a bit according to these test runs done by Tom's. It's not too terrible though, if cooling is your concern, the best would be to test it out yourself.
