Is this normal fps for a 6870 on Battlefield 3?

[endrew360]

Is my minimum fps normal for this config on 64 player conquest Gulf of Oman? Do I have a bottleneck? All High, no AA or motion blur.
Frames:46746, time:959921, min:25, max:108, avg:48.698.


Then next benchmark is played on gulf of oman again on 67 player conquest but this benchmark is shorter. I tried different settings because of this video http://www.youtube.com/watch?v=JxB01hwMouU&feature=plcp&context=C423c985VDvjVQa1PpcFOV3s-aNeTV4nQQKjGMxsMRoqSQidsMUvk%3D. It is played with with Ultra textures and terrain decoration, and medium mesh, but the others are low. this is without HBAO AA and motion blur. Frames:22889, Time:475928, Min:30, Max:73, Avg:48.093.
The FPS drops when I'm looking over the map in a heli or when there is a lot of destruction or explosions.
Resolution is 1440x900 native

Here's my config:
Mobo: N-Alvorix-RS880
PSU: Rockefish 500watt
Ram:4gb ddr3 1333mhz hyundai electronics ram, and 2gb ddr3 1333mhz elpida
CPU:AMD Athlon II X4 645 3.1ghz
GPU: HIS IceQ X Radeon HD 6870 OC @ 955mhz core/1180mhz memory @ 1.2V
HDD:1tb Hitachi 7200rpm, 320gb Seagate 7200rpm

That's an interesting benchmark and probably best if compared by you to the published BF3 benchmarks.
With the time you invested in doing this you also know that a more expensive or capable piece of hardware can improve your scores. So is this outcome good for you or do you want more performance? If you have XX amount of dollars what would you do? A $200 1920x1080 monitor might be nice but if you played at that res. your FPS would drop like a rock. For that same $200 you can get another 6870 GPU and dramatically increase FPS and/or gaming settings. BUT! That pesky Rocketfish 500W PSU could hold you back on that GPU upgrade. So, what to do, what to do? Or are you just looking for someone to pat you on the back and say, "WOW!, Great benches, endrew."?

Thanks for replying. Yeah i just want more performance, but overall im pretty satisfied. I'm just weirded out that i have a low minimum fps for a res of 1440x900. I tried using my brother's 1600x900 monitor and there wasn't that much hit in performance. I got a budget about 5 dollars since im in highschool and only get money every chinese new year. However, i cant crossfire anyway since my mobo is oem and has only one pcie x16

endrew, given your situation, you did the best you can with what you got. An admirable quality in a person.
