6950: what to expect?

post #1 of 12
Thread Starter 
Hi there, I've been out of the GPU loop for a while, sitting content with my 5850. However, a spur of the moment deal with my buddy means I will in a day or so have a brand new Sapphire 6950 (this card, specifically). So I had a few questions.

1) What increase in performance should I expect over my 5850? I'm assuming this card is only slightly more powerful than a 5870.
2) My current card is a reference model with unlocked voltage and was quite easy to OC with Afterburner. Should I expect the same here or will I have to jump some hoops?
3) Are there any current driver problems with these cards (or a reason to roll-back)? (Remember the BC2 fiasco...)
4) My mobo has the slightly older PCI-E 2.0 slot (though it is 16x). Will this affect performance at all?

Thanks

1. Should see nice performance boost especially Directx 11 titles with tessellation.
2. I had XFX 6950 2GB it overclocked good, but mine hated adding more voltage so can't really say much on that part.
3. For most people and myself 11.4 preview drivers added performance so no hurt trying those. I never had issues with 11.2 drivers tho. If you play BFBC2 alot be aware of the issue with msi afterburner locking up BFBC2 while playing.Link
4. Shouldn't really effect it.

HD 5850 @ 1000/1250 ~ Same as HD 6950 @ stock 800/1250 ins DX9/10 games. Unlocked and overcloked its ~ 30% faster, DX11 games even more, games that take advantage of the new architecture even more, 11.4 Drivers even more.

Plus you can unlock it to 6970 specs. I have mine unlocked to 900/1400 stock and it runs stable as a rock.

I don't think the card he's getting will unlock. It's not the ref v1 2gb design.

Why would you spend that amount of money on a 1gb card when you could get one of these for similar after rebate? 20-30 bucks dude... that's a case of beer you could do w/o some random weekend.

You're right, but like I said, I'm dealing with a friend and only throwing like 30 bucks on top of my 5850. The card had already been bought either way. If I was looking for a completely new card I would've probably taken that route.
