Is my computer underperforming?

I am trying to determine if my PC is underperforming or not. I recently upgraded to from an nVidia GeForce 8800 GTS to a Radeon 4890, and I didn't notice a single improvement in any of the games that I have been running. This leads me to believe my processor is the bottleneck, however, I would think I had a decent enough processor. It is an AMD Phenom 9600 Quad-Core running at 2.5ghz.

I mostly am playing TF2, WoW and CoD:Mod1. On average in TF2 and WoW, when things get a bit active with lots on screen, I will be at 15-20 fps, when in the past (on a smaller monitor and weaker hardware) I could achieve something like 50-60 with the occasional dip to the 40's.

The current specs of my system:
CPU: AMD Phenom 9600 Quad-Core
Vid: ATI Radeon 4890
Mobo: A Gigabyte Ultra Durable 3 (not 100% sure on the specs)
Ram: 4gigs
Monitor: A Samsung running at 1920x1080
OS: Windows 7 Home, 64 bit

Games I usually play at 1920x1080 at recomended settings (usually high textures, low filtering).

So my question is then, is my computer under performing, or do I need to upgrade something? Thanks in advance for any and all help.

4890 should get you 1.5x more FPS depending on game and how you setup graphics.

Reduce the texture quality should get you more FPS.

Probably need a more experience AMD/ATI guru for further help.

I'm getting FPS all over in TF2. The FPS is loosely connected with the graphics so I'm making TF2 do HDR, MSAAx2, high textures any thing else I can crank up. I rarely dip below 45fps. I found tweaking my autoexec.cfg for multi-threading made more of a diff than playing with graphics. <-- 4850

WoW is just bad because it doesn't know if it wants to be CPU or GPU limited... depends on your camera angle.

Remember that a bigger monitor + higher resolution = higher system load. Many people are surprised when they buy a new PC and it stutters at high resolutions with everything maxed out. They forget that they used to run at 1024x768 with low detail.

Guys, ~20 FPS win WOW with a 4890, even with a PhenomI, should not happen; I could manage to max WOW with a PentiumD and 8600GT for god's sake...

Check that nothing is overheating; I'd guess something is throttling the system somewhere.

@Herr_Koos: I had thought that was the case, and I think it initially was, as on my old monitor (with the 880GTS and an AMD Dual Core at alike 2.4 ghz, I was able to max frames on a screen rez (v-sync on) of 1280x1024, which then dipped to the current fps on the widescreen.) I had figured that it would improve with the massive graphics card improvement, unfortunately there wasn't much if any improvement at all.

@gamerk: Do you have any temp checking tools you'd recommend to check if its overheating?

CPU-Z Hardware Monitor is a nice lightweight tool that gives you a whole range of information, including temps, fan speeds, and voltages.

How much RAM is on your 4890? At 1920x1080 if you've only 512 you'll struggle with the res if you have high textures and AA. Though to be honest I'm not sure if you could buy a 512MB 4890 I think they were all 1GB

15-20 fps on TF2 isn't right. I think I get about 60 with a Q6600 and 4850 on 1920x1080 but I think I had to turn down the AA (but I think I'm still on 2x - I'll check later) so I would guess you'd be hitting around the 100 mark.

What about your PSU - 4890 needs 2 6 pin power cables doesn't it? Did I read somewhere that if only 1 is supplying enough juice it will run but at a much reduced rate?

Ive got both 6 pin connections on from the PSU connected to the card. From DXDIAG I have 2.8 gigs of memory on the card. And I will try CPU-Z and see if overheating is the cause.
