post #451 of 1059
Hi guys!

I have a question for you...

I recently bought a EAH6870 DCU, and I really disapointed with the performance. However, I realized that the problem is not the GPU. It's the CPU.


I'm asking if I ever, even with OC, can max out my 6870... or if instead, if I swap it back for a 550 Ti, i'll have about the same performance, considering that the cpu is bottlenecking it?


I hope i'll ear from you!
Cheers!

Since you've got the 6870 already you might as well keep it in case you upgrade your CPU in the future?

DUDE!

Don't downgrade now. Better change mainboard and cpu. In the future you can just add another 6870 if you like and you're still good.

I think they are about on par, a lot of people prefer the twin frozor just because they are dual slot. But if you aren't going for 3 way SLI/Crossfire or don't have other expansion cards then the DCII is a great choice.

I won't upgrade this cpu ou mobo... My question is as my system is today, if I'll get the same performance as with a 550 Ti.

About the same, depends on the card really. However, I prefer and trust ASUS over MSI as a company. I know they'll be around to honor the warranty in a year or two. I absolutely refuse to buy MSI motherboards (bad experiences) but that's a different story.

I heard going over 1.1-1.125 is getting into the risky voltages. Well, for 24/7 use. Crazy thing is, I only get like 20MHz more on my 560 when I go from 1.025v to 1.086v...basically my cap is 1.025v which is stock for me. I have seen plenty of people @ 1.1v. Just watch that temps. I think I got to 79C @ 1.086v, typically on stock I won't go above 73C on benchmarking and 52C in game.

Hope that helps.

it's hard to say really, as to be honest, not that many home users are still using c2d chips, maybe schools and offices, but they don't play games on them, lol...

best thing to do is find out yourself, it's pretty simple, load up your favourite games while msi afterburner is running in the background. after playing each game, check 'gpu usage' in msi afterburner, if it's not 99 or 100%, you know your c2d is bottlenecking. If your card is indeed being bottlenecked, overclock your cpu as high as possible to utilise as much of your gpu power as possible.

6870 is about 50% faster than a 550ti, so basically for your best cpu overclock, if msi afterburner shows gpu usage at about only 50%, you can safely downgrade to a 550ti without sacrificing performance. If it's in the 80s or 90s, just keep the 6870, like others have said already, it will do your a world of good when you do upgrade other components.

the limit i'd say is the max value on msi afterburner with stock bios of course. i know some people go beyond 1.15 with good temps, but personally i would not use anything over 1.1 for 24/7 use.

if you just want to up the performance while gaming, just apply a custom profile in msi afterburner beforehand rather than flashing bios. i think anywhere between 1.1-1.15 should still be safe for a few hours of gaming, but check temps and look out for artifacts
