Not at all. Asus 7870 and a hawk would be fine together

If you have enough clearance and 3 slots between graphics cards to support it, the HIS IceQ model with the semi-open blower heatsink might be better for a Crossfire config, as that can pull in air from both top and bottom, and it should exhaust more heat outside of the case than an open-air cooler. With two relatively open-air coolers, you can get a lot of hot air recycling between cards; case airflow needs to be a bit more careful unless you don't mind the high temps and noise.

I mean this:

I've never used one and YMMV regardless. Just a thought.

Youre really telling him not to buy the hawk? The most overly built 7870 for a HIS?

Thanks I'll definitely keep that in my considerations.

Hawk is much better in general of course, but it is over $40 more (if money were no object, why not a better PSU than even X Series?) and will dump more heat back into the case. On the flip side, about $50 is the difference between a lower-end 120 Hz monitor and a more decent one, e.g. Acer GD235HZbid to Asus VG248QE.

Depends on priorities and usage, like most things. You can always get the premium option at every point, but whether or not that fits the needs or the budget is a different matter.

Hey, thanks for the reply. I got the seasonic x750 psu but I might not even get around to the crossfire setup because I read that if you run games in windowed mode, crossfire gets disabled.
post #20 of 25
yes windowed mode will disable crossfire.

But why would you want to game in windowed mode?
just curios
