| | gtx 660 SLI on asrock z77 extreme 4 Little info on asrock z77 extreme 4: Slots: - 2 x PCI Express 3.0 x16 slots (PCIE3: single at x16 (PCIE2) / x8 (PCIE3) or dual at x8/x8 mode) Supports NVIDIA® SLI™ If i run 1 GTX 660 in the main pcie slot and i add another one for SLI, does the processing power or transfer rate of both cards get cut because they will run at x8? i have an i7-3770K, a gtx 660 and asrock z77 ext4 Thanks in advance guys. |

| | In terms of performance, adding a second GTX 660 to your system will only boost by about 90% graphics performance. The cards processing power or transfer rate won't get "cutted". They will simply work as a regular SLI configuration. |

| | Sir, you said "will only boost performance". is there anything else that could be increased if better cards than 660 run in sli? like 2x670 or 2x680. i know it's not a high-end card, but, do you think it's worth for me to buy another 660 and run them in sli? thank you, sir. |

| | sorry, forgot the "only", my mistake. 2x GTX 670 are better than 2x GTX 660 because the GTX 670 is faster than a GTX 660. If you need more graphics power, adding a second GTX 660 will boost your system a lot. So yes, this will be a nice upgrade. But keep in mind that some games or applications don't support multi-GPU rendering, so they will use only a GTX 660 to work. In this case, a single fast GPU should be the best choice. so, what do you need? what applications are you using? |

| | umm, i actually built this computer to run CFD, Autocad, Agisoft and others for work related. they run just fine with this setup for now, and hopefully years ahead. i also play games, that's why i asked about sli configuration. if my card can perform better with sli for years to come, then i'll buy another one. thank you very much, sir. |

| | yes, another GTX 660 will boost performance on these applications. You're welcome |
