I don't see the point in CF'ing that card, since is already faster then your entire system.

i wish i had a better psu so i can see if i can overclock it a little bit..

I don't know that model on your PSU, but watts-wise should be enough for you to OC it and you have, pretty much the best new version of the 6850, great for overclock.

it's a weird brand that's pretty much extinct here in argentina (the brand is supposed to be from USA...but... i couldn't find it either on ebay or any e-shop)

it's -80plus nothing (it's a cheap-o psu).. so i don't know if to overclock the gpu.. the f--- thing gets pretty hot when gaming... even after i turned the cpu's speed back to default ._.

i'm planning to change it (if i can get the money) for a Corsair or an EVGA one (i'll have to get it from the states via mail)....80+ psu's are non existent at the moment... we have pretty much no pc components left...last year you were able to get a decen 80+ psu.. but now a days... the only thing you have is a "topower" (a brand that i've never hurd of) thats like 1800AR$ (the corsair i found on your country's 1500AR$ ._.) i'm not tweaking anything untill i get a decent psu ....

If it stays below 70C with or without an OC is fine (with the fan/s on auto) if you want lower temps at the expense of noise (which is what I like) get MSI Afterburner and make a custom fan profile curve.

If you are in Bs As you can definitely get a proper PSU. Though Corsair is truly extinct from Arg, you can maybe find the few good PSU that Cooler Master had or the few good ones that NZXT did.

I reckon is going to be tight if you OC either component, specially that FX. So no.
IMHO, you should be putting money into a new MoBo, not a second GPU.

Guys I have a quick question. I have 2 6850's in two PCI-E 2.0 slots both running at a full 16x. On a cool day OC to 1000/1200 and a warm day 975/1200. Crysis3 at 1920x1080 with all the settings maxed out and no AA gets about 75% on both cards but the frame rate isnt actually too good. Frame rates drop in combat heavy scenes or when I turn around rapidly. Is my CPU bottlenecking my cards at all? Its a Deneb Phenom 2 quad and it runs at 4.25GHz.

Well, Crysis3 is not suppose to run good on "old hardware" AFAIK and IMHO, you are running out of GPU RAM.
post #6320 of 6939
I really want that 1GHz core clock. I know I can get there with a slight voltage increase, but this card won't let me. As soon as I pump the voltage even one tiny notch with any method (software, BIOS mods, etc) BAM, black screen of death. Sucks.
