Like many others who've posted, I want to prolong the life of my 775. I noticed NewEgg has the Q9550 for $229 shipped now, a $40 drop since I looked a week or so ago, so it's getting awfully tempting. Seems to be a mixed bag of E0 and C1 steppings in the recent reviews, though. If I were to order and get a C1, would I still see much benefit over keeping the E6750 for a few more years? I tend to keep OCing mild so it might not matter. I've already downloaded the last Abit bios flash.

I play mostly Combat Flight Simulator 3 add-ons. I've read CFX is CPU limited; not too sure about CFS3.

Thanks
 
I imagine you could O'C that Q9550 to at least 3.2 with a simple FSB adjustment in the bios, and you should notice a difference with flight simulator games.

I would think with the price of DDR2 ram being so low, dropping ~$25 for another 2gb of ram would be an even better choice.
 
I OC'd my Q9550 to 3.8 with just bios fsb changes. Four hours in P95 with no issues.

Pretty easy to find out by running task manager in the background. What res, what fps are you getting? You're probably gpu limited just guessing with what little info we have.

i dont know much about flight sims, but i upgraded from a 6850 to a q9550 on a terciary machine and it was a large bump, all else being the same.

Funny you should mention that. 2 gig more delivered today.

You're probably right. I'm at 1920x1080 with the 8800GT at 666 core and 972 memory. Core temp around 48C. Frame rate is all over the map, anywhere from about 18 to well over 100 fps, but usually about 30-70. Really busy furballs drop it below 30 fps. I tend to catch fire a lot when it stutters.

CPU Load % is generally 20-30%. Usage is about 40-60% on each core, with temps around 42.

I guess I'm just trying to rationalize a quad core. I missed out on the Q6600. I'm worried maybe the Q9550 won't drop in price any more and will be hard to find soon.
 
Your cores are not pegged so you are definately GPU limited as I have guessed. GTX260 in your price range? SLI would have been a great option should you have had the board for it, but at this point just upgrade the vid card.
 
i just ordered off newegg Q9550
upgrading from e7200 oc ot 3.6ghz to Q9550 will i see a difference
i have 4850 cf asus p5Q PRO 8gb ddr2 1

Yep glad I got the q9450 when I did, but if you REALLY want better game performance, the 260 or comparable vid card upgrade is the way to go.
 
Much appreciated. A new video card is in the plan; didn't mentioned as I'm a little unsure of subforum etiquette. I'll probably go ahead and get the 9550 anyway, combo'd with a 260 or maybe a 275, but that one might be getting a little close to my 520HX's 42A limit.
 
i don't think my e7200 oced can push my 4850 crossfire like a q9550 can
 
I just did the same thing just this last week going from an E6750 to the Q9550. My overall computing expereince has not changed, both seem to be evenly as fast. Benched both at their defaults, and the Q9550 will obviously be in the lead. Once you overclock you can really see a difference. The Q9550 @ 3.9 (460x8.5) is faster then the E6750 @ 4.0 (500x8).

Using World in Conflict:

Q9550 | Avg 65 | Min 19 | Max 199
E6750 | Avg 60 | Min 16 | Max 169

I was thinking that the E6750 able to hit 500mhz fsb would pull even with the Q9550, that didn't happen. Now its just to bad I can't get 500mhz fsb on this Q9550 and yes it is an E0 stepping, no matter how much I've tried to tweak on this Mobo (see sig) I can't get it stable past 460. Probably a mobo/Q9550 thing and I'm considering maybe picking up a P45 that can do crossfire or finding another x48 that can get a Q9550 to 500fsb.

the asus P5Q PRO is a great overclocker for cheap !
thats the board i have and i loved it
but i think iam just gonna do a mild Fsb 400mhz @ 8.5 = 3.4ghz on my Q9550 when i get it
i mostly got this chip because i need VT for windows 7 i want to be able to run xp mode
