Liquid cooling for 2x 5830 and 2x5830 or 5830 and 5870

[mak1rby]

1. what is the best liquid cooling from performance and value for 2x 5830.? is built-up liquid cooling like armor+lcs will be better and more stylish ^^?


2. which is better, dual 5830 or 5830 + 5870? I've heard some said that if 5830 & 5870 Cf-ed, the 5870 performance will be same as 5830.?

editt :
what psu will be enough for 5830x2? is 720 watt enough?

and

is coolermaster elite 335 casing enough for 5970?

THANKS before.

and, sorry if my english is bad.

If you mix a 5870 and a 5830 all the performance you will get is equivalent to two 5830s in crossfire. It would be in your best interest to just use the 5870 rather then crossfire two 5830s.
