Any thoughts? My only concern is my chipset is the z77 which means im going to run in 8x 8x instead of 1 full 16x. Let's just assume that all the cards are 2gb vram with an average core clock of 1150 Two questions:
1. Is it worth the investment? As in, I probably wont have to upgrade until the 800 series?
2. Would 2 gtx 670 even saturate a 8x 8x bus width?

CPU shouldnt be a concern. 3570k OC at 3.8

I somewhat agree that a GTX 780 would be a better choice than a pair of GTX 670s. For one, I prefer single card solutions to SLI if the performance is similar. You're going to use more power with 2 cards, have more heat and not all games respond well to SLI (The games by the big developers almost always will though).

It's difficult to compare the 770 to a pair of 670s though. The 670s should thoroughly outperform a 770 and will cost $200 more. Not an even comparison.

One thing to keep in mind, Nvidia just announced they will be releasing a new card in November (GTX 780Ti) that may drive the price down on the older lineups. Maybe the prices won't be affected much, or at all, but if you're not in a hurry you may find yourself with a...

Do you understand what saturating a PCIe bus means?

In regards to the PCIE bandwidth, you wouldn't notice a difference between 16x/16x and 8x/8x until you got into ultra-hd resolutions. Even then it's not going to make a noticeable difference in gameplay... perhaps a 5% difference.

I recently added a second GTX670 to my rig. I am using an i7 950 at 4.0ghz and EVGA FTW mobo. I tested them in 16x/16x and 16x/8x. In order to run them in 16x/16x I need to have them in slots 1 and 3. In that configuration the top card runs WAY too hot! Regardless I was able to run 3dmark11 and Heaven benchmarks with both cards running at 1202 core and 7200 ram. I then ran the same benchmarks in slots 1 and 5 which is 16x/8x. With the cards seperated the temps are much better.

Anyway, I got almost the exact same results in 16x/16x as 16x/8x. In fact I had ever so slight higher numbers at 16x/8x. The numbers were close enough for it to not matter. I averaged 91 fps in Heaven, everything maxed at 1920x1200 and 14950 in the basic 3dmark11.

So don't worry about 8x/8x. You will still get excellent performance.
