I have a DP45SG Intel MB with PCIe 2.0 x16 ports. My CPU is a Sandybridge Q6600 not the newer Ivybridge. Is there any charting on the impact on performance of the GTX 770 GPUs when running in this configuration? Am I at a point where I need to upgrade the MB as well?

No - PCIe 2.0 is not going to bottleneck you on Single GPU setups.

You will have a bottleneck with your Q6600 though. (and it's not Sandy Bridge, its a Core 2 Quad Kentsfield)

If you O/C that Q6600 to 3.5 GHz or so, it will allow you to play pretty much any game but will still bottleneck that GPU from everything it has to give.

If your running your Q6600 stock, your really bottlenecking that GPU.

Your ready for a CPU/Mobo/Ram upgrade.

It will be held back by your CPU for sure. You'll need to start thinking about a total upgrade of everything. Motherboard, CPU, memory.

That's an LGA775 motherboard with P45 chipset. Your CPU is completely outdated for a graphics card of the 770 level. Nothing above HD6850/GTX460 is going to be useful on a stock Q6600.

If you are going to overclock the Q6600 to 3.4ghz, then you could step up to maybe a HD7870/GTX660 at most. Otherwise, I would strongly consider a full system upgrade.
