Default Quick question relating to 4850's

Should I get the factory OC 4850 IceQ4 (650/2000 vs 625/1986) or the one without OC I plan on buying 2 for a CF setup and they are both the same price. Or maybe I should go with 1 4870? I do plan on running 1920x1200 in games though.

Between the 2 4850's if they are the same price you might as well get the Turbo. Great card by the way. Now one thing to think of is if you get 2 4850's you are done right there. If you get the 4870 you could add another later.

I could always just get 2x 4870's at the same time later as well when they drop in price in 6-12 months, how much hotter would the turbo run compared to the one that's not OC not that it is even OC very far

I don't know what the regular one idles at but mine is idling at 54degrees right now with and ambient room temp of 22degrees. That's with the fan at default in a cramped little RC 330 case.
I killed my comp that had this card in it yesterday and have moved it to my comp with no games on it yet. I will have to look for the catalyst 8.10 again as it allows fan speed control.

I'll install warhead and find the new catalyst and get back to you. With the fan turned up a bit it was still quiet and dropped the temps quite a bit

I doubt the OC one those cards affects temperatures at all.

You can probably OC way beyond 650/2000. I have my HD4850 (Arctic Cooling TwinTurbo) running 700/2200.

What motherboard are you using to Crossfire these one though? If it's a P35, I'd advise against using Crossfire. If its X38, X48, P45, you're good to go.

I did some testing with both the 8.9 and 8.10 drivers. I did one pass of 3DMark06 for each reading.

These idle at 500/1000 no mater how you set them.

The 8.9's idle at 54/55 degrees (d).

The 8.10's I tested with the fan at 20% (lowest possible) and 80% (at 81% I could just barely hear it over 3 tri-cools on lowest speed so I stuck with 80%).

The 8.10's idle at 50 d with the fan at 20% and 38/39 d at 80%. Notice the lower temp on the 8.10's idle, it makes me think the 8.9's fan spins at less than 20% when idling.

I tested both drivers at 625/1000 (as close to the non turbo version as possible), 650/1000 (stock turbo speeds) and 690/1125 (comfortable overclock without mods).

625/1000
8.9's gave a high of 67 d
8.10's at 20% 71 d
8.10's at 80% 53 d

650/1000
8.9's 67 d
8.10's at 20% 81 d
8.10's at 80% 53 d

690/1125
8.9's 69 d
8.10's at 20% 79 d
8.10's at 80% 55 d

The 8.9's only vary by 2 d on load so I am assuming the fans ramp up a bit according to temps. I couldn't tell for sure because I can't hear it at all. These are so much quieter than my 8800 GTS 512!

Note that these are not average temps but highest temps reached. I paused for a few to 5 minutes between each pass to let temps stablize. I hope that helps you or anyone else wondering about the HIS 4850's.

My Sapphire HD4850 dual-slot fansink version idles at 35C, with 37% fan speed for idling. During load it hasn't hit over 70C (not sure what fan speed)
