Pros: Got this to replace an aging GTX 560 Ti. Slotted it in, booted up, global driver picked it up and I was good to go within minutes. No additional setup required. VERY quiet. Not hearing the GPU fans roaring when under load was a breath of fresh air.
Cons: It's a big. Had to rearrange the drives in my tower in order to give it enough space. Minor detail, but make sure you properly account for its dimensions if you don't have much breathing room.
Overall Review: If you're trying to choose between the 770 and 780, get the 770. Best bang for buck and you won't be missing the extra power from the 780 for most practical gaming purposes.

Pros: Quality is fine, no defects out of the box, plug and play.
Cons: The stand is made out of what appears to be cheap plastic and the base is snap-on without any way of tightening it. The result is a really unstable monitor. Even the slightest movement of the desk causes the whole thing to wobble wildly. Very disappointing for what would otherwise be a very good monitor.

Pros: Bought two of these. Very crisp image, great colors, the glossy surface is barely noticeable so long as you don't have any bright sources of light behind you and the contrast is perfect right out of the box. Base is stable, doesn't wobble at the slightest movement of the desk as some other monitors do. Inclusion of cables for every supported video input is really handy.
Cons: IPS viewing angle doesn't really live up to the hype. Looking at the screen straight-on (90 degrees), there is a noticeable difference in contrast between the top and bottom halves of the screen. It's worse than the TN-panel I replaced. Text is a bit harder to read and colors are dimmed on the bottom half. Image is very dark immediately after waking from standby and it takes a good 30-60 minutes before brightness reaches maximum. Especially obvious if you have two of these side-by-side. Buttons along the bottom of the monitor are pretty stiff, to the point of having to hold onto the top of the screen in order to properly actuate them. You'll rarely be using these buttons, so minor detail.
Overall Review: Inexpensive IPS monitor - you get what you pay for. Not the best out there but it does a fine job for gaming and browsing. Avoid if you absolutely need fidelity.
