Well, after today's news from nV. I've decide to just not wait for the fermi. I dont think its going to be anything earth shattering anyway. but now I have the cash set aside to do some upgrading. I only get this opportunity once a year during tax time. I was thinking of 2X 5970. But I have a feeling that I would be creating a bottleneck. so the question is should I get these cards and do some overclocking of the CPU. Or should I just upgrade something else and just be happy with these 2 5870's I have. Question? Will 2X 5970's be bottlenecked by a stock i7940 2.93 GHz. running 5670 X 1200 resolution. will I need to overclock this CPU. If I decide to go this route My original plan was to throw these 2 5870's in my other computer and put the GTX 480's in this one |

I'm planning to do a comparison/review of the 5870, the Eyefinity6 and the 5970 when ATI has the hardware ready for me. I never got into the 5970 as Full CF+EF support didn't come out until just the recent 10.2. I don't think I'll get enough cards to do a CrossFireX setup on the 5870 or the EF6 card, but I can provide some comparison numbers on these single cards on my i7 920 at stock speeds. |

Cool, I always see reviews with Overclocked CPU's . Which is understandable as you want to see the full potential of the card. but seeing one at some stock speeds would be a nice comparison. I'm even beginning to wonder if I'm not getting some bottlenecking already? Your comparison/review of those cards on a stock 920 would be a nice treat. |

Your cpu is already holding you back a good bit. The performance numbers between stock and OC'd i7's is pretty sick. They are capable of 4ghz with little to no voltage increase. I am pretty sure even the demo systems AMD uses when showing off systems with 2-3 cards and Eyefinity are heavily overclocked. |

Quadfire is bottlenecked by the CPU almost all the time, at least from what benchmarks I've seen in the past. A quad GPU setup will almost always see a boost from a further increase in CPU speed... Having said that, I'm sure there are some games out there now that are more GPU limited in that scenario (mostly from lack of VRAM...) |

You can see what I've done so far by clicking the Benchmark link in the upper-left hand. Still have more games to test, and more stuff to post. |
