Before the latest expansion my FPS in 25-mans stayed north of 30 fps on Ultra settings, I quit for about 8 months and recently came back for patch 5.4. For some reason in 25 man raids my fps now drops down to between 5-10 fps. When I glance at my second monitor I notice that my GPU usage is matching my FPS number to number. If I'm getting 5fps, my GPU is at 5%, If I'm getting 15 FPS the GPU is at 15% and so on. My CPU during these FPS drops will only be at 75-80% load. To help alleviate this problem I turned the graphics down to medium settings (except view distance, textures, and env draw) and now everything runs fine.
I'm 90% sure that my CPU is the problem here, no L3 cache, very small L2 cache, and being an AMD, OC'd 3840 mhz is pretty low too. I was considering buying a new Intel I5 CPU and motherboard, but instead I bought a FX-6350 (all that my budget could handle) I almost bought the FX-4350, but I like to have Itunes, Hulu or Netflix playing on my other monitor and I figured that despite a 300mhz loss, the extra 2 cores would help out with that. The new processor should be at my door when I get home today.
What kind of performance increase should I see with this processor? Besides WoW I play games like Skyrim, AC3, Dishonored, Tomb Raider, BF3, and probably BF4 when the price comes down.
How much of a "bottleneck" has this CPU been on my GTX 580 Lightning?
My computer is setup as follows:
ASrock 990FX extreme4
4x 4gb Corsair XMS3 2000 mhz
1x MSI GTX 580 Lightning (OC to 900 mhz)
1x Recon3d PCIe sound card
1x AMD Phenom II X4 840 @ 3840 mhz (20% OC)
1x Corsair H100 (2x AP120 fans)
1x OCZ Vertex 3 128gb SSD
1x WD 1tb storage drive
1x Corsair 700gs PSU
NZXT Phantom case with both top exhaust fans, 2 small side and 1 big side intakes, 140mm front intake, rear exhaust (h100 mounted under top exhaust fans with AP120s mounted under pushing up)
1x 23.5" Acer 1920x1080 1ms
1x 20" Acer 1600x900 1ms (for HW monitoring)
