Thread: Is my Processor Bottle necking My Cards?

I have the 955, and I can’t say sufficient good things about it. But, I think that a quad core that is decent would contain a hard time bottle necking those two cards, but it might be bring them a little. The 955 would be an ideal match for the 5870, and 1 5870 possibly is close to equivalent to 2 4870.

I'll obtain one of those off your hands if you don't require them both! Well, I'd quite much only desire a Vapor-X model, though, and they're sold out essentially everywhere!

The CPU might be bottlenecking, dependent on your resolution. Can you overclock your CPU a bit? If so, attempt it at like 3GHz and observe if your frame rates go up.

Yeah attempt OCing your CPU but if you ask me you'll desire a Phenom II to continue with 4870 crossfire. Just recognize you won't perceive much of an augment in performance, if at all, using a 5870 compared to 2 4870s. With the omission of games that are only optimized for a single GPU of course, but those games should be over playable on yet a single 4870.

Thanks for the replies friends, sorry I overlooked to state that my processor is a Phenom II, my motherboard supports AM2+,i recognize that the phenom 955 is AM3 but does support AM2+,but I am thinking that I would not actually observe any presentation gains as I would not be running it to its possible. I am ok at building pc`s but I have to say that I am a complete noob (or nob loll) when it arrives to overclocking anything. I only built my pc about 8 months before so I don’t want to fling to much more money at it. I’m playing Dirt 2 at the moment and that appears to run better with the one card apposed to crossfire, that’s why I was thinking of going to a single 5870,as ares1214 mentioned one of those is more or less equivalent to two 4870,but as I said if the processor it not quite up to the potential of the cards I may as well remain what I have, plus they are only directx 10.1,games are now pending out in direct 11,holy its hard to stay up loll. Thanks again for taking the time to reply.

Dependent on some belongings here.
1 is, at 512mb on your cards, the 19x12 will have a big result.
Anything under 3 GHz with a Phenom is causing slow downs and a 5870 wont provide you the oomph you’ll desire, unless you obtain those CPU clocks up.
IMO this also plays to the 4870s as well, as they’d indeed observe some nice perfections with higher clocks.

Do you signify 512mb on my cards?, if so no they are 1gb each and thank you for the linkage and the respond, looks like I have acquired to step into the world of overclocking.

Yeah, with those 1 Gig cards you’ll be well, just knock those clocks.

Well I have clocked my cpu to 2.9 GHz and put the most recent drivers on my card and holy fook, it was as glitch as hell, but as soon as I dropped it to a single card yet again it was fine, maybe Dirt 2 does not similar to crossfire. They say that in crossfire you only add about 30% presentation, so if I was to get a single 5870 would that not advance my presentation? The reason I say that is that two 4780 are more or less the similar as a single 5870 but in crossfire I am only ahead another 30% but if I had a single card with the control of two would I not get better presentation because its not two cards relying upon a bridge to link the two card together?

I imagine after the drivers have developed on the 5870, you’ll perceive it as fast as or a little faster than your system in CF. Plus anything DX11 will be faster also.
