Re: Going SLI worried about heat.
You may want to wait and try them.....you may be surprised as I have just went to GTX 260 in sli and just by turning the fan speed up to 70% the highest the cards got was 73c on Crysis
Other games it is cooler than that.....I ordered a 120MM case fan to put on the side of my case to blow cool air on the cards.....this will do fine I am sure.
You may want to try them out before you spend $100 on new heatsinks.
When I was running my gpu fans at 40% the cards got to about 78c at times in Crysis.... turning the fans up to 70% from 40% dropped the gpu temp 5degrees for me.
