Advice for crossfire and/or cpu upgrade??

post #1 of 6
Thread Starter 
Hi Guys,

I'm currently running a Core 2 Duo E6750 (2.66GHz) with a solid overclock to 3.33GHz., and a XFX Radeon 6850 Black Edition (factory overclock). This rig has run most everything pretty admirably, except some bearable, occasional choppiness on Assassin's Creed 3, and now I'm running Crysis 3 at around 25-30fps on medium settings. I'm itching for a performance boost so I can bump up the quality settings and boost my framerate as well, so I've been searching eBay for another 6850 to run in Crossfire. I've heard of people essentially doubling their framerates with a Crossfire setup. My question is, will I be facing a serious bottleneck issue due to my CPU? Enough that I should consider also upgrading to a Core 2 Quad? I really don't want to go thru the hassle and expense of upgrading my mobo as well, so maybe getting a Q9650, Q9550, or something similar on eBay is really the only feasible option, they seem to be going for around $100... Is it even worth it to upgrade the CPU, or will I still see a huge improvement with the Crossfire setup anyways with my Core 2 Duo? Please see sig for further system specs.

Thanks for any feedback.

If you want better gaming performance dont bother cross firing, sell it and buy a better GPU.

If i'm correct that a dual core right ? Soon most games on PC now require quad at least.

Cross fire will just give you a dirty bottleneck but upgrading your CPU instead of GPU you wont see bigger boost when comparing to crossfire or a newer GPU.

You will get a better performance of a 7850 then crossfire, you can just sell your old card and with the money for new card buy your self a better GPU then CPU.

Well if you're dead set on keeping that setup and going with another 6850 i think youd really need a quad. But honestly i would not bother getting another cpu on that socket nor another 1gb card.

In my opinion id see how much you can get for your setup and put that towards a new build.

@ deathdeal3r & Bluemustang,

Thanks for the replies, I appreciate the advice, but I'm not really looking to drop a load of cash on a new rig right now.... just was hoping to run Crysis 3 at highest settings at a comfortable 40fps maybe... maybe a different GPU is an option for being a little more future-proof, but from what I see, an XFX HD7850 2GB is over $200 on Newegg, and is it really gonna give me that much of an improvement on my current rig to be worth it over getting another HD6850 on eBay for like $100? I'm really trying to weigh price vs performance, as I'm not a serious gamer who needs the latest and greatest.

I think a 6850 would get you your money's worth...you might have to live with 2x AA for some of the very latest games, but that is still plenty. However, for anything that is a year old you will be rocking the house at 1080p. My single 580 is still doing everything I throw at it...the most sacrifice I've had to make is 4x AA, but I don't have any of the latest games yet.

Though I am pretty sure there are a couple Q6600's on OCN market place at a good price right now...you might want to consider one. It would get you to a quad core very cheaply and there are times when four threads are nice to have these days...as the new consoles come out I'd expect those times to become more frequent.

You won't get 40 frames (maybe max) with any budget build at max settings. Even my sig rig drops below 40 fps maxed out and thats a 3570k+7970. Crysis 3 is extremely both cpu and gpu intensive.
