Alright so a buddy and I built our gaming pc's together 3 months ago. He had a bit of a bigger budget than I did so he went and go the i5 2500 and I decided on the fx6100 by AMD. I was going to go with a phenom chip but wanted to save a bit more money. We also both got the gigabyte radeon hd6850, both got 8 gb of kingston elite limited edition ram, the only difference in the systems were the HDD and the processors.
Today we decided to put our systems side by side and play some bf3. Both had the exact settings. First was ultra with no AA. We used the render.drawfps 1 command in game to show our FPS. We would go stand in the same area and for some reason I had a standing avg of 76 fps, and he had an avg of 72 fps.(we were stanind in the same spots on the maps. He had a 4 frame drop. While running or moving in an area with lots of action I had an avg of 59 fps and he had 56 fps. again he was losing 3 fps compared to mine. We have both processors at stock speeds.
With AA on I was getting a moving avg of 34 fps while he was getting 31 fps. We checked out our drivers, we have the same drivers for our GPU and same chipset drivers for our MOBO's. In theory he should be getting better performance from what we have seen in benchmarks but it doesn't not appear that way.
Could the HDD cause a drop in frames? Again I dunno how they would change anything as my HDD speed is slower than his.
When we overclocked we only did a bit to 3.7 ghz and I was again beating him by a couple of frames.
Could there be a reason for this? we had no programs running in the back ground, and both on the same internet connect..
