Hi I am almost done building my system and was looking at the numbers and not seeing the number i thought i would be seeing, what do you guy think should i be getting higher number then this.

System spec.

CPU FX8120
Mother Board Gigabyte GA-990FXA-UD3
Ram Mushkin Silverline 16GB (4x4GB) DDR3 1333MHz CL9
SSD Boot Drive Corsair Force Series 3 90GB
Hard Drive Seagate 1TB

Oh! yea and my top video card gets up to 104C and my CPU is being Cooled by water cooling setup, see my other thread.

Thanks guys for all your input.
 
I run a 1920x1200 monitor with 6850s in crossfire, and pull much higher numbers than you seem to be pulling.

I will go fire that machine up and double check.

But what cpu do you have

phenom 2 x2 @ 4.3 ghz.

you need to overclock your cpu, I can't break my nephew away from the computer long enough to benchmark anything.

And seriously, real talk, buy a good monitor. There is no point in running crossfire and AMDs top cpus if you have to run at shit resolutions.

monitors are the single best investment a gamer can make for their rig, close second is gpu.
 
So any members with like systems. Could give me some benchmark numbers that would be great.
 
Crossfire 6870 at 1280x1024?! WHY!?

A single 6770 would power through anything at such a low res.

dose any one have any benchmarks for me with a system the is almost the same?

Honestly, while you might find someone with similar hardware, it is highly unlikely that anyone around here is using that kind of hardware with a monitor with such low resolution.
 
you are cpu limited because of your insanely low resolution. there is absolutely no friggin reason to run crossfire with that resolution.. hell even a single 6870 is to much for that resolution. get a new monitor!
 
you need faster memory for one... get a 1866 or 2000Mhz set and youll see at least 6-7fps...
 
OH MY GOD.

I use a SINGLE HD 6870 for gaming at 1080p. It's a great card, it's in the mid-high end range and is pretty close to the HD 5870 at stock, and mine even surpasses the stock HD6950 @ 1015mhz / 1172 OC.


WHY ON EARTH WOULD YOU USE CROSSFIRE FOR 1280x1024??!! WHY?


A single HD 6870 is enough for 1080p. What the fuck are you doing?
 
Sadly, you will need to put yourself through the hassle of moving over to intel to achieve the level of performance you are deserving of, and expecting. Before you or others cry foul. Let me be the first to apologize, but to also point you to Google where you can search and find that I am absolutely speaking the truth. I came over from a system basically like yours. From a AMD system with x-fire 5870's and the performance was horrid. Once I went to a 2600k, I saw 100% .... 200% ..... 300% increase in all my games. It's the AMD cpu that's holding you down, I assure you.

a 300% increase from going to a faster cpu? lol, not unless you were coming from a single core A64 or P4.
 
My bad. It's 1280 x 1024 and how would going to high rez incresse my FPS and give me a incresse in games that have a decresse.
 
Crossfire was never really ment for a single/low resolution monitor, its simply not needed. Nearly all $2-300 graphics cards have the HP to run any game on the market @high or Ultra settings at 1280x1024. Most people who run Crossfire rigs are using a 27"+ monitor and/or multiple displays AND high resolutions. In short, what they are getting at is your CPU is bottlenecked with that much GPU power behind it. The only way to see more FPS would be to Overclock the piss out of your CPU OR upgrade it to an i-5 or i-7 AND overclock the piss out of them.

This.

AMD went piss-poor for gaming with Bulldozer- your CPU claims it has eight cores, but in reality it has less raw FPU throughput than an AMD X4; and it's less efficient by most other measures, particularly IPC. That means that you either need to significantly increase clocks, or swap the CPU. The former is faster, easier, and cheaper. A decently OC'd BD 8-core should be able to properly feed an HD6870.

Of course, then you need to get yourself a real monitor.

At that resolution all in all what you are seeing is your cpu bottleneck.

You can see that you get almost 100% performance improvement with crossfire when talking of pure graphic tests. I wouldnt advocate a jump to intel on account of already having a full system, but i can assure you that you oughta see around the same fps numbers all the way to 1080p+

you are playing at such a low res that your cpu is taking a crap dealing with all of the additional overhead associated with running multi gpus. you could easily get the same framerate or better at a res like 1920x1080. buy a modern monitor or sell one of your cards.
 
I have been thinking of going eyefinity with a 1x3 set up but dont think I would have a good time with this my system at the resz

i also use a 19" dell lcd 1280x1024...

p6910 in 3dmark2011 with my single 7970. i would overclock the 8120 to at least 8150 speeds
 
You're getting low scores because of the low res. If you take a look at the various benchmarks on analysis sites, you will notice that the higher the resolution, the more FPS you get on a high end setup. Sounds weird but it's just how it works.

You kind of setup is intented for higher than 1080p gaming, so, you're clearly overpowered right now and are losing a lot of power bacsue of your monitor.

I'd say even an old HD 4870 would be enough to play any game at maximum on your 1280x1024 monitor.

I'd get a 24" monitor right now if I were you! Or, I suggest you give me one of the cards. I'll give you my address, you ship it to me. I'll pay shipping. I promise I'll put it to better use! Deal?

Going to a 1920x1080p monitor will not increase his FPS, but will move the bottleneck from his CPU to GPUs. I have never seen a review where the FPS Increased simply because the resolution increased. More pixels = more work...

using a low res with multi gpus can actually cause a small loss in performance due to the overhead just like I said.
 
I have a HP 22" on my son's computer I think its 1680x1080 or some thing like that. I well swap out and retest he is only running a X1950 pro

thats what I thought it would use more video memory

This!

Time to stop investing in graphics cards and start investing in a monitor with a res of at least 1080p.
 
should be easy for someone with a 6870 CF setup to run at 1280 * 1024 to give him something to compare 2, instead of questioning him why.

I'm sorry, but Crossfire with such a tiny resolution is just silly.
Who would even provide benchmarks this day and age with that resolution?

It's hard to find benchmarks with 1680x1050 at this point.
Most Crossfire benches are shown with 1080p and above and/or multi-monitor resolutions.

Yeah, we are wondering why he is using such an old monitor.
Sell one of those graphics cards and get a new one, problem solved.

Not to be mean, but this is kind of noobish imo.

Never judge a person by their sig. ;)

I've seen plenty of people who own Porches who don't know shit about cars.
I've also seen people who own sub-compacts who are experts in cars.

You know what, it's not my job to sit here and tell you the obvious, that is, that Crossfire is totally unnecessary with a single monitor @ 1280x1024.
Have fun with that setup of yours.

I find it funny that a guy running an Atom knows more than a guy running an FX, zomg. :rolleyes:

I don't have alot of money and 3 kids to boot. over the past 8 months i dumped $1200.00 +/- on my new computer so far. I have to build slowly to make it afordable. I had a phenom x4 9750 with 4 gb and a raid 0 set up and a X1950 Pro then i went to a HD6870 then bulldozer and SSD WIN7 64bit 16GB Ram then second HD6870 and new 850W Power supply and want to make sure that everything is working the way it should with what i have now. Then down the road maybe in a month or two i well buy a new screen or three, but thats some thing else i have to look at is if 1 GB is ok for three screens.

yea but do you have any handson with crossfire or processers in the upper half

or is it just from all info that you have read?
