Guru put them all thru the paces and the conclusion on performance, temps, OC are remarkably close. In fact the load dBA from the MSI is a touch quieter.
I have a PCS+ and Tri-X, a buddy had a pair of MSI Gaming (he returned them due to temps), we have the same case setup, Define R4s. The PCS+ won't hit 68 at load at stock. It won't come close. You won't hit 68c even with a beefy overclock. Here is Far Cry 3 all night, ambient 22, with a pretty good overclock (1170 on the core, up from a factory overclock of 1040) and high fan rpm:
If I run close to stock with a 1090 oc, I can turn fans to basically silent (40%) and get temps like this:
It's not just me, go check out temps in the Powercolor thread, nobody is hitting 68c on the core without a big overclock and vddc adjust. Meanwhile my buddy's MSI Gaming in single gpu would game at low 70s core, high 70s/low 80s vrm1. The Tri-X isn't as good as the PCS+. But it's pretty darned good too. Here is my crossfire temp picture after a 50 loop of Metro LL bench maxed, ~22-23 ambient:
Gaming temps, Far Cry 3 for 3+ hours, ~22-23 ambient:
I'm surprised you're able to run quad MSI Gaming xfire on air. What are your temps like?
Anyway my buddy's MSI Gaming in crossfire always hit 90c on the top card at game load in minutes and throttled. He's not the only one with that experience. I'm not ragging on the card, like I said it's fine as a single card gpu and it's quiet. And it's the smallest 290 by a big margin which is nice. But I think your experience is aberrant. Over at OCUK there was a big thread about MSI Gaming and high temps which is what made me wait for the PCS+ and Tri-X, unlike my impatient friend.
Sorry for the long thread, the hwinfo screens take up a lot of room, but I stand by what I said: Powercolor PCS+ runs 15-20c cooler than the MSI Gaming, and the Tri-X is not too far behind. This PCS+ cooler, is quite possibly the best gpu cooler ever made. I certainly have never owned a card that gets temps like this.
