Ati Sapphire Radeon HD 4870 Crossfire problem or what?! - Page 3

post #21 of 44
doing a gpu "only" bench will still be improved by getting a faster processor. Your GPU might be doing all the work in a video test, but it cant crunch numbers any faster than the CPU can provide them.

If you have any doubt feel free to compare GPU benchmarks from my sig rig, I use a 4870 OC'd to 800MHZ, technically not a faster GPU than yours especially not two of them, but paired with a faster processor. These tests do rely some on CPU but mostly GPU dependent.

Aquamark 3: 148,873
3DMark 06: 15,897 3DMarks

Have a GPU only test you want to compare? provide a link and I will run it.

I am getting a Q6600 today.
When I get that I will do a dual gpu test and a single gpu test and see if it still has the same results. Than I can basically conclude that I need a more powerful PSU?!
I am going to take the 3DMARK 06 now

I would be surprised to find out that your psu is the issue. Not everything scales well with crossfire. You mentioned Dolphin (the wii emulator) from what I hear that is one of those apps. Even in the apps that do scale well you also aren't going to see 100% scaling. I would run Heaven and see what sort of difference you see or some game that is known to scale well.

An intel e5200 even overclocked is not going to run two of these video cards at their max, you would be fine running one- but that CPU would be somewhat bottle necking one 4870 let alone 2.

Put your money on a CPU upgrade, get a C2Duo or C2Quad with lots of L2 Cache

they are right about your PSU not being the best in the world, but chances are its running everything just fine and you dropping money on a better PSU could have been better spend buying a better processor. -me, been there done that.
Dude, it's a Wolfdale at 4ghz.

E5200 only has 2MB of L2 cache

Q6600 8MB
Q9450 12MB

clock speed alone does not determine performance, Core 2 CPU's are more efficient and do not need to run as fast to achieve the same results as other "pentium" CPU's

Dude it's a low cache wolfdale.

Those core2quads don't have shared cache so the Q6600 really only has 4mb of l2 cache per dual core. Q6600 is just two Allendales spliced together.

As I said I saw no difference in my Wii Emulator. It could be that my CPU is holding back my Emulator? But even on a game such as Counter Strike Source, the FPS is the same as with 1 Graphics card as apposed to Both Graphics cards.
