Mark,
No problem. I may have misunderstood your tone. I apoligize if I seemed, sensative. Moving past that, I hope you can get your benchmark rig back up and running. The results you post will have me re-consider my position. Currently, you can purchase 2 460's stock and after rebate you will have paid around $320. That is a pretty good price to be able to obliterate a $500 GTX 580.
We are all sensitive. You have to realize my
excitement in revisiting multi-GPU in a big way was just overflowing. Very recently both AMD and Nvidia have been playing up their multi-GPU scaling to the point of it appearing hype. What surprised me - for newer games at least - is that the scaling is not hyped; it is greatly improved in my experience over what i previously experienced.
Using 29 games, all but two have very good scaling - and the two that are weak don't need it (except for GTS 450) - and most games have excellent scaling.
My PC is running OK except for the ATX connector's 12V yellow wires overheat to the point of melting the PSU's connector; something must have failed or my Gigabyte x58 MB is badly designed to not have a power connector directly to the MB besides the CPU and ATX connectors - clearly the PCIe slots are not getting enough juice for GTX 560 SLI. i will telephone Gigaybyte today to see how their RMA process goes. Slowly, i heard.:'(
i have finished (single and multi-GPU) testing GTX 560, GTX 460, GTX 450 and HD 5870 CrossFire. i got HD 6870 CF set up and it runs fine (the wires don't overheat so badly as the GTX 560Ti SLI) and perhaps i can finish that testing and write a shorter article to show how lower and mid-range multi-GPU testing compares with powerful single GPU solutions (GTX 580/570 and HD 6970/6950). Part two will cover GTX 580/480 SLI vs HD 6970/6950 when i get my MB back (hopefully Gigabyte has a solution, or it will melt again)
