I currently have a HD 7970 and have to make a decision...should I crossfire or trade the 7970 I have for a 780 or a R9 290. Also if you think I should please let me know if it should be a 7970 or a 280X. I plan on getting a 1440P monitor this Christmas also. I play things like BF3/4, Crysis, Borderlands, BioShock for example.

Thank You for all constructive input.

Possibly, but those are $700 plus USD. Thats is out of my price range. What would you pick from what I listed and why.

2 x HD 7970s will out perform a GTX 780 by a lot. And the new AMD beta driver (13.11) pretty much has micro stutter eliminated with their new Frame Pacing. But be sure your MB has at least x8, x8 PCIe x16 slots. If the 2nd slot is just x4 bandwidth, you will loose a lot.

Check your MB manual to be sure the slots you want to use are both X8 bandwidth. The board's web site doesn't specify. However, it does say the last slot is only x4.

I have 2 3.0 PCI X16 slots.

EVGA GTX780 (967MHz base)

Crossfire still has a ways to go, nor is SLI perfect either. There are still stutter issues, nor is Crossfire working in DX9 last time I checked (2nd GPU runt issues resulting in both stutter and 30FPS perceived frame rate not 60FPS).

It's not as simple as looking at the benchmarks.

Additionally, the GTX780 has three great games:
http://www.anandtech.com/show/7430/nvidia-announces-hol...

Shadowplay: records 1080p 60Hz (I never dropped my frame rate at 78FPS VSYNC OFF to test).

PHYSX: not a huge deal maybe, but you are missing something in games that can't play it. I turn it off in some games though.

G-SYNC: this is a GAME CHANGER, so I advise you to WAIT on your monitor if possible. http://www.anandtech.com/show/7436/nvidias-gsync-attemp...

G-Sync is NOT a minor thing. I studied computer and I can tell you it's simply awesome. For example:
"Next up was disabling v-sync with hopes of reducing stuttering, resulting in both stuttering (still refresh rate/fps mismatch) and now tearing. The G-Sync system, once again, handled the test case perfectly. It delivered the same smoothness and visual experience as if the we were looking at a game rendering perfectly at a constant 60 fps. "

2560x1440 vs 1920x1080:

I have a 1440p (many have issues BTW), but I actually game mostly at 1920x1080. Why? Because the difference in many games is next to nothing but with a 30% frame rate hit. If you are at 60FPS VSYNC'd a better card can also produce less stutter; it's a misconception that all 60FPS VSYNC'd experiences are the same.

I play Starcraft 2, Torchlight, Dragon Age and several other games at 2560x1440. Basically small HUD/TEXT which looks a lot better at 2560x1440. I can also maintain those at 60FPS anyway.

But Crysis 3 at 2560x1440? Better than 1920x1080? Only if you're looking really close and even then you wouldn't likely notice during a game.

I have an Asus GTX680 DC2U (comparable to an OC'd 770) and I've played pretty much every game. I tweak to maintain 60FPS (50FPS in Crysis as it's supported). The quality difference between what I can maintain and the absolute BEST isn't really that huge, and with a single GTX780 you'd do better.

I hope this is useful.

Summary:
- EVGA GTX780 (967MHz base) $500
- 3 games
- PhysX
- Shadowplay
- G-Sync
- 2560x1440 vs 1920x1080.

Trade 7970 with 290(non x), it will give u 30% performance increase and can handle any game at 1440p. This will save u from dual card problems.

I'm not a fan boy of either camp but I do like saving money =o) I had a 550 Ti before this 7970. I played Borderlands 2 maxed with PhysX. It did make things it was coded for i.e. moving water and bouncing boulders look smoother than my 7970. Only slightly though. In response to your G-Sync bullet what about Mantle? I know we know very little about it but what if? I'm not trying to say Go Red Team!, but play the counter advocate as well. Lastly, you said you had issues with 1440P; would you just get a 144Hz 1080P monitor instead if you had to do over?

g-sync is going to be MASSIVELY EXPENSIVE

It seems like nvidia guys loved getting ripped off. I don't get it. They must get good allowances.

Some people have short-term/selective memory and forget the days when the 7970 was being sold for $550-$600; and the GTX 680 was cheaper and faster than the 7970; and then a year later when the GTX 770 was cheaper and faster than the 7970 GHz.

Honestly, the first card I bought was a 550 Ti when I started PC gaming with a 720P TV, when I got my 1080P monitor and 7970 I was wowed. I have been allotted some money by my awesome wife to upgrade my rig. I'm thinking of getting a 144Hz 1080P additional monitor, although I do have a friend who is all about 1440P. Still working on that one. Of course a major factor is prices/money but I would like to have something that will tear thru games. I play mainly FPS game and of course Skyrim. I read what everyone else reads about the new tech coming out and know that future proofing is almost impossible, but I'm trying to get the most out of what I can.

Now that I see you are playing Skyrim, then Crossfire should be immediately ruled out, and AMD cards in general as well. Crossfire frame pacing does not work for DirectX 9 games, which means that dual AMD cards will only give the performance of a single card (i.e. a waste of money).

In general, Skyrim performance favors Nvidia cards. But another little known fact is that Skyrim fundamentally looks better on Nvidia cards. Only Nvidia cards allow you to enable Ambient Occlusion in Skyrim, which effects nearly everything in game as it improves shadow quality, realism, and depth. In the image below, Skyrim on AMD cards looks like the "AO: Off" screen:

Then what route would you take? I play Skyrim on and off again. Apologize if I made it seen as it was my goto game. I know its a dirty word but for "future proofing" would you crossfire what I have, get an nVidia card, or get a better AMD card? I honestly don't know what route to go....

Plus G-Sync will be included in some monitors at first..ASUS 144Hz I know. The board will also be sold separately for 100 - 150 USD. That's not too bad...Before you bring out that Mantle or alike will be free....that's like comparing tennis to bad mitten.
