Crossfire GPU's only getting 40-60% Usage on certain games?

Hi Guys,
Just setup my crossfire and has been going brilliantly on most games but I just loaded up Borderlands 2 which really is not demanding. Brought up the OSD and my GPU's are only getting 40-60% Usage with 80-100FPS in big battles when it is very hectic. I am using a 144Hz monitor so going crossfire was mainly for getting more frames out of my games.

Another thing is when I am out of hectic situations the usage goes right back upto 80-99% usage achieving 200-300FPS?

Not so worried about keeping a solid 144fps, I find 100fps smooth enough but when it drops down to 60fps or below it does my head in!

I don't want to believe it, my heart sunk once I read these replies. Only built this PC (first PC) in Jan this year, not sure if to try and return my CPU to Amazon or sell it and put the rest of the money towards an i7. Being a noob to all this I guess we all have to make mistakes to learn! :(
Pointless me sticking to an i5 as I have just bought this new GPU and it would mean I could get the same performance from a single GPU heavily OC.

Tom
 
Ebay it is!
I'll put a reserve on so it does not go for pittance, having a look around Ocuk at the CPU's and why are the Sandybridge-E and Ivybridge-E soo expensive, is it the fact they have six cores?

Tom
 
Well the main reason I bought a new GPU was for the next-gen games as I know a single 7950 will not give me significant frames. Do you reckon most next-gen games will be very CPU demanding or opposite?

Tom
 
IMO just keep what you got. Overclocked i5 doing 70-100fps may be bottlenecking crossfire 7950 or 7970 which can fly over 120fps+ in some games at the moment, but with the new consoles around the corner, I think new games will have your crossfired cards dipping their capability down to the same 70-90fps level as your CPU soon enough, thus balancing out the CPU and the graphic card performance. You could always increase the AA level with your spare GPU usage (even if the x8 AA over X4 AA might not be that hugely difference).

Ummm, see what you are saying but wouldn't a i7 still boost the performance?

Tom
 
Got ULPS disabled in Afterburner so that's not the cause but like you said next-gen is going to require an i7 to take full advantage of a dual setup. Also when you mean CPU progression is lame, do you mean they could be making something so much more powerful?
That's the one thing I do not understand, before I bought the second GPU I researched into finding how much of a bottleneck there would be on CPU heavy games like BF3, people were getting 80% out of i5's so why is it that I am all the way down at 40-50%! Big difference!

It would IF the game use more than 4 cores/threads. I just thought it ain't worth the hassle of having to sell your i5 to change to a i7. It's definitely worth considering, but only if you can find a i7 for cheap enough, and you don't mind going through the trouble of selling your i5.

If it was me for the sake of 120/144Hz monitor, I would go all out going IvyBridge-E 6 cores if money is not an issue.

Was looking at those Ivybridge-E CPU's, tempting but a lot of money. I would also have to buy a new Mobo as mine is a 1155 Socket. To be fair, I need to sell a bike I have which could get me some money together!
How much of a performance boost would I see with a 6 core CPU Next-Gen?

Tom
 
You should also expect a lot more games to start using more than 4 threads because both the new consoles will have 8 cores as standard.

Yeh, that was one thing I was thinking of but then wouldn't a i7 struggle as it has 4 cores?
It is either sell my i5 and get some sort of i7 (probably 3770K) or overclock my i5 heavily. The thing is will overclocking my i5 make much of a difference because I thought the main reason I am bottle-necking is because of Hyper-Threading?

Tom
 
Yea that's was my initial thinking when I mentioned the IvyBridge-E 6 cores (but they sure are/will be dam expensive), but looking back OP is only talking about Borderland 2 specifically, so I removed my suggestion.

No sorry, I play all games including Battlefield, Crysis, Valve games etc. Basically don't just play one game, I like to play a variety of new releases and old.

Tom
 
Farcry, Payday, Bioshock, Dishonored, Saints row, Tomb Raider, GTA, Fallout, Splinter Cell and soo many others! xD
I literally play everything, I could go down the whole list but it would take a while.
Games in the future that I am looking to get:
BF4, Watchdogs, Prey 2, The Division, Wolfenstein, Rainbow 6 Patriots, Theif, Titanfall (this especially).

Tom
 
Get an i7. Fire and forget. Although it might not be the case in every title, if your gpu's are only getting 60-75% usage then what's the point in having two of them?

Exactly, thought about returning my card earlier and just sticking with the one but with next gen coming up I would soon regret it.
i7 it is!
How would an Ivybridge-E or Sandybridge-E compare to a 3770K?
Silly money for a Sandybridge-E but just curious really.

Wait... I know that the I5 can bootleneck 2x7950 in crossfire... but that much? 50%???

In most games it does, Just been playing CS: GO and it actually seems worse then a single GPU, both GPU's are working at 30-40%, 180fps. Also when I get into hectic situations it drops to 100fps which never happened with my single GPU.
Seriously need an i7!
