7950 Crossifre

[rare]

Just wondering if any of you guys have any experience with a 7950 setup on a z68 motherboard.

I am seriously considering it, though I am aware it won't run in true 3.0 x16 crossfire. My understanding is that this won't make a huge difference to performance though?

I was looking at 7970's but 7950's at 1ghz or so which should be easily achievable should be a cheaper yet still very powerful alternative?

Also wondering if micro stuttering is still an issue with these cards? Far as I can tell it tends to be luck of the draw? I never experienced it with 285 SLI setup I had before?

3.0 is about 5% at the very best faster than 2.0.

What you need to take into account is that no GPU set up in the world has yet used up all of the bandwidth on PCIE 2.1, let alone run close to 3.0.

Like many other things (DDR3, USB3, SATA3 etc) it usually takes a good while for them to really come into their own. Some things (like triple channel DDR and quad channel) were never what they were cracked up to be.

I mean, two GPUs at 8x 8x are about 7% at best slower than dual 16x lanes.

Tom @ OC3D did some experimenting with PCIE 3 in a video, will see if I can find you the link

Here y'are mush this should see you right

Some 'if not all' P67/Z68 are PCIe 3.0 ready you just need an Ivybridge CPU and it will allow PCI-E 3.0. It's literally of case of an Ivybridge CPU and a bios update, you might be lucky and your current board support PCI-E 3.0.

With regard to micro stuttering, ive used Crossfire with two cards and used a HD 6990 before, didn't experience micro stuttering with either setup.
