Thanks in advance guys. I am a new member, so be gentle. :)

In April 2011 I purchased this:

BioStar TH67+, 16 GB Ram (DDR3 1600), i5 2500K

I am running Windows 7 with a 256GB SSD. I use this machine almost exclusively for Adobe CS6 (Photoshop/Premiere Pro). I am not a gamer, so I don't worry about FPS on Crysis 2 or anything like that.

At the time I was not worried about a dedicated video card. Now that my CS6 work has ramped up.. I am really missing some hardware acceleration. So I purchased the GTX 770 (because I heard the more CUDA cores the better for CS6)

So now I have all of the above and a GTX 770 will arrive today. BTW: I also have the following PSU: Corsair TX750W 750-Watt Power Supply - ATX, 140mm Fan, SLI-Ready, SATA-Ready, 80Plus

Here is my dilemma. The H67+ only has PCIe 2.0, and the 770 supports PCIe 3.0. Will the 770 work with the H67? If so, How much performance, if any, will I miss without PCIe 3.0? Also, I do not think I can overclock with the H67+, which I think I could squeek out some additional performance from CS6 if I OC'd.

Does it make sense to upgrade to a new motherboard to get PCIe 3.0?

If I get a new motherboard, should I bite the bullet and get a i7 4770K and a Z87 to go with it? (about $500) or just $80 - $150 on a Z77 and toss my H67+ board?

I think with either new board I will get the max 1600 out of my current DDR3 (running at 1300).. so some performance improvement there.

If I go with Haswell I will move all of my current components to upgrade my UnRaid Server. But that's not my priority.

So in summary...

1) Will the GTX 770 work with my PCIe 2.0 H67+ motherboard?

2) Will I see a performance improvement if I get a Z77 board?

3) Is the performance improvement of the Z87/i4770k worth the ~$400 difference vs. the Z77?

My bottom line is.. having just put out $420 for the 770.. I would prefer to wait the next generation processor if I can get away with it. Either way, I would like some assessment of the performance I may gain with these options and I appreciate the advice of the community.

1) Yes, it's backward compatible.

2) Not really (or not enough to justify replacing your board)

3) Once again not worth it IMHO.

If I were in your situation, I would keep everything as it is. The i5-2500K is still an excellent CPU today. The 3rd and 4th generations of Intel "i" CPU only brought marginal improvements (like 5 or 10% better compared to your i5-2500K so this is why I say it's not really worth the money). Or if you want fill the gap you could simply overclock your i5-2500K instead or replacing everything, but I would wait a couple of years before getting a new board + CPU, because your setup is still very good.

One very important question: You didn't mention what PSU you have? It's very important for your video card that you have a PSU with enough power and enough PCI-E power connectors to hook to the card. But I guess you already checked the requirements for the 770.

By the way, PCI-E 2.0 shouldn't bottleneck your card, or if it does it will be by a very small margin and you're not likely to notice it. The additional bandwidth that PCI-E 3.0 provides become more important when you use 2 or 3 video cards at the same time (SLI).

Thanks, I updated my original post to include the following PSU: Corsair TX750W 750-Watt Power Supply - ATX, 140mm Fan, SLI-Ready, SATA-Ready, 80Plus

That's an excellent PSU. So no worries, all you have to do is add the GTX 770 and your system will be good to go for at least a few years before thinking about an upgrade.

Funny thing is, when I say that's what I would do if I were in your shoes, that's kind of true because I'm pretty much in the same boat as you. I have a i5-2500K with an Asus board (H67 chipset too) and a Corsair TX-650v2 PSU. Only difference is I use the PC to play games and I currently have a GTX-460 which I'm thinking about changing soon. But I'm very happy that the rest of my build is still holding on and that I don't have to replace the board or CPU for at least a few years. I'm probably looking at getting a GTX 760 or 760-Ti which should be a good upgrade for me.

Enjoy your new card!
