Got a new AMD HD 6870 for Christmas today. Plugged it in, installed latest drivers, all that greatness.

also got a new HDD, so it was a fresh install of everything.

After installing Crysis and TF2, i began to notice some sub-par FPS then what i've seen in reviews and videos.

My Rig:
AMD Phenom 9600 Quad-Core, 2.30GHz
4GB of RAM
Windows 7 Home Premium x64
Sapphire Radeon HD 6870

I run all of my games at 1920x1080 on a 27 inch monitor.

Thanks for any help in advance guys, i look forward to your responses.

well more than likely your hitting a bottleneck with your processor, seriously youve got to overclock that, i guarantee you if you verclock to 3ghz or 3.5 you will notice a big improvement

Another thing some people have done when they first install their new AMD cards, is to turn all the settings up in the CCC. If you turned on Supersampling AA mode, you'll kill your performance in games that are demanding.

Supersampling AA is great and all when you can use it, but you won't be able to use it a lot of games.

Do you know what m/b and psu you have ?
Gamer is correct, your cpu is holding it back.
The original phenom's do not o/c well. Most have their l3 cache disabled because of the tlb bug. Slowing them more. http://en.wikipedia.org/wiki/AMD_Phenom

Maybe you can upgrade to a newer AMD cpu ?

Money is tight at the moment for upgrading sadly, lucky enough to get the GPU lol.

750w PSU, not sure of the branding..

Mobo is an ECS Black edition of some sort, cant seem to find the box =\

I'm rather unprepared haha


Thanks for all the help so far guys.

I'll do the OC'ing ASAP and get back to you with results

It would be great to OC that CPU to 3GHz, but as a PhI, it will be lucky to reach 2.6-2.8GHz.

What frame rates are you getting? It could be that you simply have reached the limits for your CPU. Any review showing the 6870 will be using a highly OC'd i7 or PhII chip, which is way better then what you have. Best bet is to use what you have, and upgrade your CPU (and mobo if you need to) when you can.

There's your problem:

AMD Phenom 9600 Quad-Core, 2.30GHz

2.3ghz simply cannot keep up with hd6870.

Completely agree. Your CPU is not good enough. First off, the first Phenoms had a TLB bug that implied deactivating the L3 cache. Then the manufacturing process and architecture and the TLB bug didn't allow it to be produced with high clock speeds. Even the ones that came after the TLB bug had been fixed topped out at 2.5 and 2.6 Ghz. And these original phenoms don't even have much L3 cache anyway; only 2MB versus 6MB for the Phenom 2 line. They were not even able to match the Intel Q6600.

If I were you, I'd try to sell that CPU second hand for a few bucks, get rid of it while it is worth something, and buy a fast triple core Phenom II. Get something over 3 Ghz.

You'll save money over a quad, and not lose performance, since almost no games take advantage of 4 cores (Metro 2033 and GTA IV do).

The HD6870 is too good for that CPU. An HD6850 would do the exact same job, so, consider upgrading the CPU, otherwise the extra bucks you spent on the more expensive GPU will never materialize into performance. For now, consider running at a max resolution of 1680x1050 (or 1600x900 is your screen is 16:9), or even 1280x800 (or 1280x720 if your screen is 16:9) for more demanding games like Metro 2033 and GTA IV.

I really appreciate all the help from you guys, any idea what place I could sell it, or a good replacement???

Mobo is an ECS A780GM-A, 750w PSU and all that good stuff

Not easy, because as I said, money is tough right now.

Edit: Link to my MOBO http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail...

It's AM3 ready, so im looking at a AMD Phenom II X4 955, 3.2GHz

if you cant overclock, your best bet is to live with it until you get enough money to get an athlon II x4 - check to see if your motherboard will support that cpu.

The Athlon II X4 would be better than what you have now because it's faster, but remember, it's no faster clock for clock than Phenom 1, your on the right track, save your money for the Phenom II X4.

Yes, Phenom II; the Athlon does not have L3 cache, so you wouldn't really see a big benefit going from your to one of those.

Buy a Phenom with all the L3 cache goodness. If you can afford the Phenom II X4 955, 3.2GHz like you said, the better. That's a good chip, and unlocked, so and you can even overclock it to 965 or 970 levels (3.4 and 3.5 Ghz respectively) That will put it up against a Core i5 750/760.

Even at stock it is probably all the midrange performance goodness you need to pair with that graphics card!
