I pulled the trigger on a Gigabyte 5850 today. It should suit my needs for a while and a nice upgrade from the 8800GT.

I snagged an XFX 5850 Black Edition and I'm running it with a 9600GT for physx. It's a nice combo for my 22" monitor. Your 8800GT would make a great physx card too.

I wish my 8800GTS hadn't died. I would have ran that as a Physx card next to my EVGA GTX 206 SC.. alas I can't :(

ooh, benchmarks anyone?

Go here to see the interesting evolution and hierarchy.

One thing will stop me, well two actually. I gave my card to my mom and my budget mobo doesn't support SLI. My thinking at the time was I would never go SLI for the performance vs dollar thing but it never dreamt you could use a second card for physics alone.

I have the 5870 black edition and i think it is a great card. i love how smoothly the multi screen stuff works now

I used the Radeon Bios Editor from TechPowerUp! to mod my bios and allow higher overclocking higher in CCC. My 5850 BE is rock solid at 840 core and 1250 mem. I haven't done any voltage tweaking..... yet. But, I've been doing a bit of reading and do intend to try MSI Afterburner out. It looks like nailing a 1GHz GPU speed isn't a problem. In Vantage using the performance preset I got a gpu score of 16351 with my current clocks.

EDIT!!!! - I made another modded bios tonight. I was able to increase my voltage using the RBE and adjust the CCC overclocking headroom even further. I slapped the gpu up to 1.2v and was able to bump it's speed up to 950Mhz no prob. I tried 975 and 1000 quickly for kicks and vantage crashed both times. The gpu score in vantage at that setting was 17362. I didn't see any performance increase in Crysis Warhead though. So I went back to the other bios I modded for OC headroom only, and left my gpu OC at 840MHz in the CCC. I figured there's no point in creating more heat just for benchmarking.

A few things I learned about these cards lately. OC'ing the crap out of the ram will not produce artifacts because these cards will just re-send their info until it's processed correctly before it's displayed. So too high of a ram OC will just slow the card down. You have to find the sweet spot by checking for a decrease in FPS, and not by looking for artifacts.
This one I'm not 100% sure of but I read that too high of a voltage increase on the GPU won't hurt the 58XX series cards. It supposedly automatically protects itself against high current and extreme VDDC temps.

Thanks for the info. I haven't gotten my card yet. Today will be 7 days ago I ordered it. I see it landed in Concord ON last night at 1 am. I doubt then it will make it here today.

Bah, my card is still a dud for overclocking. I threw an MSI unlocked bios and an asus unlocked bios.Ive gone as far as throwing 1.4v at my card and cannont get this damn thing to budge past stock clocks.

What bios's did you use killswitch?

I used the original bios that's already in my 5850. I made the changes I wanted with this. -> http://www.techpowerup.com/downloads/1770/TechPowerUp_Radeon_Bios_Editor_v1.25.html
It's easy. Just yoink the bios from your card. Make your changes. Save it. Flash it. Presto!
Keep a copy of the original though. Then you can always flash it back to stock, or you can use it to start over and make another modded bios if your previous one isn't quite up to snuff.
