Hey,

I am not sure whether to buy a 5850 and o.c. it or shed some extra money to buy a 5870, which then if I o.c.ed would be far ahead of a 5850. I'm really trying to get the best so down the line I can just crossfire it. Which do you think would be better a little ways down the line? So if I was to go with either which brand would you recommend? I really just want a card that runs cool and is good for overclocking. A card I had in mind was the Sapphire Vapor-X 58xx any input?

Depends on budget. How much can you spend?

I do not like to OC GPU's. I figure they run hot enough.

Brand? For ATI, I like XFX.

The 5870 isn't as good at overclocking, and an OC'd HD5850 performs better than a stock HD5870.

Get two ASUS CuCore models of the HD5850 for $320, and crossfire another one later. Two non-reference crossfire cards will be capable of massive performance.

Thanks that helps a lot!

+1 to Shadow. 5870 at $100 more isn't enough faster (especially with OC overhead) to warrant the increase in price. Plus, they aren't that hot that OCing them will be a big issue.

The 5850's overclock really well, I'm able to get mine to 922/1200 on stock voltage and 1000/1200 with 1.2V :)

Yeah I agree with the extra $100 or more dollars not really being worth the performance. Do you guys think that down the line two OCed 5850s will still hold there own? Or do you think if I was going to perhaps go the 5870 way it would make a bigger impact in the future?

Also in terms of what 5850s are the best for OCing is the Asus one the only one you can tweak the voltage with? Any other brands you'd recommend?

MSI has their on as well, a Twin Frozr edition. Their Afterburner is quite renowned, and the companies are on the same level.

As for your first question;

2x HD5850 OC will do ~ 2% better than 2x HD5870. Though 2x HD5870 OC aren't bad either.

2 OCed 5850s should be pretty darn good for a good while. You can actually flash the BIOS and do voltage tweaking on many of them, but I don't have one an haven't done it, so I don't know which ones work best for that. Probably easiest with the ASUS since you don't have to worry about voiding the warranty by flashing, plus they generally have solid cooling. Whatever the case, the Sapphire cards generally have pretty good cooling, so that might help your OCing, also- XFX has the double lifetime warranty in North America, so if you live in the US or Canada, that'll be good for you too. some of the MSI boards have the extra OCing features as well- good cooling and I think voltage tweaking.

Yeah flyinfinni, MSI has their program called, "MSI Afterburner," that's used for Voltage Tweaking OC'ing.

Only reference cards (and ones that specifically advertise) can increase voltage.

And omgitzfatal, just out of curiosity, did you try an OCCT error check on your card? I thought mine was 100% at 825 (never crashed, all looked good) however it would get an error or two in 10 min. A little bump in the voltage, now it passes 10-15 minutes w/o error at 850.

Alright thanks this really helps! I think I will probably just go for one 5850 for now the crossfire it later. Thanks again!

Sounds good man- enjoy:-)

Have fun with your new card!
