Question concerning Xfire 6870's

post #1 of 4
Thread Starter 
Hey all,

I'm looking into xfiring 2 6870's in my current build. My issue is that my motherboard does not have two pci-e slots. SO, my question is this:

Should I keep my current CPU and simply get a new motherboard/RAM (any recommendations) and another 6870? Or would I be better served to upgrade to an i5-2500k (would need to buy motherboard, cpu, RAM and another 6870).

I know that the i5 has much higher performance, but is it worth upgrading from a Phenom II? I know that I would definitely get a greater benefit from a GPU upgrade, but because my motherboard is lame and I made poor choices in my upgrade paths in the past, I'm stuck at this fork in the road.

EDIT: Also, is it possible to run a card for physx along with crossfire if I have enough slots?

1. Yes it will be a substantial upgrade over your current CPU / motherboard combination if you go with a 2500k
2. Its possible to have a dedicated Phsyx card with an AMD setup, but not usually the easiest thing to do as you have to run two sets of drivers, have hacked drivers, etc.

Man, I already spent $400 upgrading my case, psu and video card. It's going to be another $600 if I go the i5 route (when all is said and done). Sadness. I really want crossfire though. Why didn't I give myself options when I upgraded to my Phenom II? =(

It is not only possible, that's what I have in my system for years and it doesn't anything close to complicated than to install a graphics driver.

Only 3 steps:
1. Intall Forceware 258.95 (no restart).
2. Install PhysX System Software .514 (no restart).
3. Run the PhysX patch (restart PC).

Verify using GPU-Z if Physx is checked, it will work for all the applications with PhysX hardware acceleration.

Done.
