I've really had no problems with ATI Crossfire, so I wouldn't worry TOO much about that. The only thing is that in 3 years time, I have a feeling DX11 is gonna be a pretty real deal, and you'll be wishing you had it before then- might not be, but thats my guess as it really does change a few things. Also- if you are going to get a new Mobo, then you might as well just get a new CPU as well. No point in upgrading an old mobo to another old mobo- too much money to be worth it. Save money now, and get a new system and DX 11 sooner.
What would you guys recommend for a motherboard as the best chance to get my q9550 to 4ghz, I have a cooler that could handle it I need a motherboard that can and some luck. I'm stuck at 3.4ghz with this old gigabyte 965p-ds3.
If I'm sticking to ddr2, is crossfire not worth it on these mobos?
I have been looking at the benchies... 2x 4890s do pretty damn well, and my current 4890 can do 950/1150.
2x4890's is truly a killer amount of power. They were a killer deal too going for $200 new. If you can get a second for a good price, go for it. I just avoid buying used, so as cards get harder to find at retail they sorta fall out of my view a bit:-)
Get a good brand x38 or x48 board and you should be set. DDR2 version would be best so you don't have to replace your RAM, but yeah.
