GTX 560 Ti SLI OC'd vs HD 6950 1GB XFire OC'd

post #1 of 19
Thread Starter 
Which one would be a better choice? I plan to OC the **** out of them and was wondering how they fare against each other.

Im guessing your 6950's would win that fight since you can unlock em, but then you lose out on physx/cuda.

Exactly.

HD 6950s (unlocked) would beat the **** out of GTX 560.

But you'd lose both in-game PhysX and Folding&Home.

That's a real tough one. Like Jedi said, you can unlock the 6950s, and they're faster for being only $10 more.

However, for overclocking, I'd say the 560s. They have insane overclocking potential and scaling on the new Nvidia cards is very good. The 6950s are already at a decent clock rate so you won't be able to get much from them. The 560s on the other hand, can go past 1000MHz without any voltage bumps.

6950 1gb can't be unlocked unlike the 2gb version.

But I'd say the 6950s would win also. After OC'ing to 950+ mhz, the GTX 560 performs on average 3-5% slower than the 6950 at 1920x1200 and 2560x1600. After OC'ing the 6950, that gap goes to 7-10%.

Currently, AMD an Nvidia both have great scaling for 2 cards, so that shouldn't be a factor. However, I have heard reports that crossfire has more bugs than SLI, but I can't verify that myself.

So the 1GB HD 6950 XFire then? They probably won't unlock to 6970's until a good BIOS comes out.

As many as I need to figure this out.
