Time to leave nVidia? - Page 2

post #11 of 54
1. You should get a reference XFX, Sapphire or Gigabyte Radeon 6950 2Gb. Non reference cooling usually helps, but you should consult reviews. Though, the reference cooling is pretty good.

2. AMD drivers are fine, but if you plan on going crossfire, they will start to become annoying. AMD drivers have tons of Crossfire driver issues. You'd lose PhysX and CUDA of course, so if you play any PhysX enabled game, that's a loss.

You will also use a lot of developer support too. Most games favor nVidia cards, some heavily.

3. It is fully compatible with your socket 775 motherboard, and your CPU should not bottleneck your performance... even when clocked only @ 3.3Ghz.

A pair of 6950's is a total waste at 1200P for a single monitor.
6870's would be a better option, or just one 6950 now.

A single GTX 580 will max out everything at that resolution. A single 6950, not so much.
It also has superior tessellation/onboard PhysX and CUDA and a much more solid driver set. Its the fastest single GPU solution by far and thats why the price tag is what it is.

1. If you want to unlock, you need a reference model card. Something like this. This is the cheapest reference model you can get, and it unlocks the hidden 6970 shaders.

2. Drivers are pretty much the same quality for both AMD and NVIDIA nowadays. With AMD, you do gain Eyefinity (the ability to run three monitors off one single card) but AMD cards are worse for Folding@Home. Because of the 2GB frame buffer, it's also better at very high resolutions like 2560x1600 or 3840x1080/1200.

3. You won't bottleneck a single Radeon HD 6950 at current clocks but to get the most performance out of it you should over-clock your CPU to around 3.8GHz if you want CrossFire with no bottlenecks. Just push your CPU a bit higher and you're fine for CF.

Can you send me a link to a good unlockable 6950? Im sure id screw it up and pick the one without the BIOS switch, given my recent luck.

so can i with a gts 450

Gta iv isnt the best test

1. Get a reference 2GB if you plan on unlocking the extra shaders.
2. The 11.4 drivers are outstanding. Do you actually use PhysX and 3D vision? Most people don't so it's more of marketing hype.
3. Your CPU is fine. It's your resolution that matters more, and at 1900x1200 you will be pushing that GPU hard enough.

So before i do anything rash, i want to consult you guys with a few questions.

1. What model should i look at if i want to unlock? Are there some that cant? Would going non reference cooling help?

2. What would i lose/get by going ATI (drivers, PhysX, 3D vision, stuff like that)?

3. Also, if i got it now, could i install it in my current system w/o a bottleneck with my CPU?

Thank you guys so much for being the best forum ever.
I've heard a few issues with the unlocking... I wouldn't be quick to jump on that if I were a 6950 owner. Good luck to you if you decide to go with it.

2. Drivers-wise, I've heard more complaints of AMD's drivers, at least compared to Nvidia, but I've also seen plenty of counter-examples where people have a perfect experience. It's the same with Nvidia; as long as you do proper installs of drivers, games, patches, etc., you'll be dandy. You'll be giving up native PhysX support, but it's not very widespread and generally not considered a loss; if you really want it, there are workarounds for getting it to work with AMD's cards. You'll be giving up 3D Vision, but you'll be getting Eyefinity support in return; your call.

3. Though an "i7 Q9550" doesn't make much sense, you'll be fine with your current setup. "Bottlenecking" is usually exaggerated, and it's only experienced in relatively few scenarios.

The 6950/70 is definitely a solid card, though it's sad to see one leave the Green ranks

It's not a good value proposition at all, though. I think that's what the OP was getting at. And no, a pair of 6950s is not a total waste at 1920x1200 with AA/AF. You'll gain 60-80% more performance than going single card. Drivers are mature now, so no problems there. A stock Radeon HD 6950 CF will trash a GTX 580. Also, drivers are just as good for both. We're not in 2007/08 anymore.
