7970 upgrade to.. for a 1440p system

TBH it doesn't matter what he goes for he may well get some bottleneck due to his CPU but the 7990 offers the most graphical power for his money so even with the bottleneck he will still get more performance than what a 780Ti or 780 or titan or 290/290x can offer. And he asked for the best single car for his money regardless of red or green team so the 7990 is the winner regardless of the excuses.
 
I made the jump to 1440p this year and my gtx680 gave up entirely. Can't reccomend the 7990 enough, blew me away with just how powerful it is for the price. Doesn't drop below 80 (Max 140, avg 95-100) fps on BF4 Ultra with 2xAA (not really needed at 1440p).

Coil whine was there when it arrived, its significantly reduced now after some mining.

If you do get one, make sure you have sufficent exhaust fans. I've had to take the side panel off my Carbide 540 to keep it cool and quiet.
 
What experience?

You're dismissing what the developers of the game are saying without any evidence at all. I'm saying that what they're saying may actually be true, I hardly think that is the same.

He has tried an 930 at 4Ghz with SLI 670's and reported he got a bottleneck. Don't make out that Mantle will stop this when you know as well as I do that Mantle is so far 0 games. End of subject for me, as I was just making the OP aware that he WOULD SEE A BOTTLENECK with his CPU at 3.8Ghz. I didn't like him being told to ignore any bottleneck talk, as Mantle will sort that, when it possibly will in BF4 but can the same be said for all the other games that are out?

That was on BF3. Things have improved on the bottleneck side because of Directx11.1 and Windows 8/8.1.

BF4 was only ever talked about. I certainly never said there would be no bottleneck on his CPU with other games. And testing an i7 with SLI 670s has no relevance to Mantle performance at all, so I don't see why it was brought up as talking from experience vs. my implied lack of.

People are putting too much faith in Mantle this early on, has anyone considered that it may not run very well with all CPUs. Older CPUs like an i7 930 may have problems compared to the latest 4770k.
 
The bottlenecks i experienced were with bf3, and with 4 being a more demanding game it will be more pronounced. The old bloomfield chips were great but are starting to show their age when combined with more recent cards in sli/xfire. Tbh ive even experienced a good difference between the cpu in sig with theese cards and a previous 3770k at 4.5ghz. As for mantle, we'll just have to wait and see proper results when theyre released. Too much rumour/speculation at the mo. If though it delivers fair play to amd.

My friend who found his 2500k bottlenecked his 7850 crossfire setup in BF3 reported that under BF4 and DX11.1 there no was no bottleneck and both gpu's gpu usage was close to 99% gpu usage more often than not.

EA-DICE' upcoming online shooter Battlefield 4 will take advantage of DirectX 11.1 API, on PCs running Windows 8 and Windows 8.1. Running the game with DirectX 11.1 will have a positive performance impact compared to running it on DirectX 11.0, or on older operating systems like Windows 7 (which doesn't support DirectX 11.1). In the words of the technical director behind Frostbite, the underlying engine for Battlefield 4, "We use DX11.1, there are some optimizations in it (constant buffer offsets, dynamic buffers as SRVs) that we got in to the the API that improves CPU performance in our rendering when one runs with DX11.1.

A fundamental part of the design of Mantle is to allow parallel execution across 8 (or more ) threads. This isn't based on the raw power of the CPU, but its ability to run multiple threads.

"For starters, Nixxes' Katsman revealed that "very early figures from Thief" (which is "not fully running on Mantle yet") showed a big reduction in draw call overhead. "Before, we would often see about 40% of the CPU time stuck in the driver, in D3D, or in various threads," he said. "The early measurements we did, right now we have that down to about a fifth of that."

"DICE's Andersson extrapolated upon that same notion in his keynote, saying that, with Mantle, the CPU "should never really be a bottleneck for the GPU anymore." In a separate demonstration, Oxide showed their Mantle-enabled space game suffering no frame rate hit when the FX-8350 processor on which it ran was underclocked to 2GHz, or half its base speed."
 
Matt/Teppic, if you feel that Mantle will eliminate bottlenecks for CPU's (which I believe it may well do in Mantle games), that is cool but not sure on the amount of games out but I do know that BF4 is one of hundreds, possibly thousands? Modern games that use the CPU well like Hitman/Tomb Raider/Sleeping Dogs/Crysis 3/Arma III (I hope he doesn't play that with buying a 7990)/BF3 to name but a few that will see a bottleneck and not allow the 7990 to be fully utilised. I think the 7990 is a great card and regardless of what I am saying about a bottleneck, I feel it will be ideal. No TrueAudio though, as that is only on the 290/290X I believe? and Mantle for Thief and BF4 to look forward to.

I can see that some people believe that Mantle is so good, it will in fact become Skynet.. :D
 
Nobody was talking about anything but BF4...

If people think Mantle will help with games that don't use Mantle, there's no hope for them.

Ignore any talk of a cpu bottleneck. Mantle will solve that for you. You have an i7 and mantle is gonna love 8 core/threaded cpu's.

I was.

Because you and your mate were talking about BF4 only, that doesn't mean that no one else is allowed to mention other games.

OP buys his 7990, gets it home, fires up Tomb Raider, disappointed with the frames, no need to inquire, as he is now aware that the CPU is bottlenecking.
 
The thing is though Greg most games won't bottleneck it. There are only a few and they're typically worst case scenario ala bf3/crysis 3. 99% of games will be fine.

You seem to be arguing for the sake of argument, so I'm out :)

I'll bail out here as well.
 
Still should get better frames per second vs what ever else is on offer for the price though even with a bottleneck. Either way OP needs to update his rig either with a good overclock on his CPU or upgrade. :)

The internal workings of an i7 930 are different from a 4770k, this could lead to all sorts of problems and it would be unwise to think Mantle will work well on all CPUs from the last 5 years without tweaking. Lets see Mantle running before we jump to conclusions.
