Upgrade worth it? New mobo and 2x 4890?

hi just sell your card and buy a 5850 or 5870 or gtx 400 when prices go down. cf is better on x58 platform you will be loosing performance on p45

If you have a PCIe 1.0 x 16 or PCIe 2.0 x8 for both Xfire slots, you should be fine with 2x4890s.

2x4890s would perform great and be better than a 5870. You can get a 4890 used for about $150-$160ish.

you have a good point sir but he will be stuck with pretty much old tech and the next upgrade he will probably be taking is 3 years from now. further more power hungry cf

set up and ati cf driver problems could be stumbling blocks down the road... just my 2 cents  

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.

+1 4890 crossfire (unless dx11 tickles your fancy) if your mobo can take it. Your CPU is fine, i'd wait until you are ready to change sockets before you buy a new mobo.

Realy?

I ahd thoguh used proces went up from 150$ to like 175$ each.

As much as I am an advocate for DX11, 2 4890s is an insane amount of power for the money and they overclock almost as well as the 5xxx series, just get another and a decent board.

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.

Any X38 or X48 board will do.

^ Be sure not to get a DDR3 X48.

Doesn't really matter, DDR2 isn't much cheaper anymore.

I guess since you already have DDR2 it is a good suggestion though.

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.
