After installing my new video card, I promptly ran 3dmarks06 And got a score of 2226 over 174 (lol) with the FX5200.
However, the performance in games, namely WoW and CS:S are still the same as with the FX5200. I'm averaging about 20 to 30 FPS regardless of the video settings ( High med or low).

The rest of my specs are:

2.9GHz Celeron
1GB DDR400 RAM.

I've got no spywares viruses or anything so I'm quite puzzled as to why I'm getting such low performance on those not so recent games.

Did you remember to remove the old FX5200 nVidia drivers and install the ones for the 7600GS? That could be important. Your CPU is quite weak, but it shouldn't bottleneck the 7600GS nearly that much.

Your CPU is serverly limiting performance. I suggest you turn up the graphics a bit, as the Celeron only has a 512k L2 Cache it makes it extremely weak for games and applications. Hence why your not noticing a difference in performance.

Download driver cleaner pro and clear all the old drivers and do the restart and then install fresh drivers - see how that goes and post back.

I believe Ive read around that WoW is very CPU intensive, its possible you are being limited by your cpu rather than your graphics, a 7600 will take just about all that Wow can throw at it at lower resolutions.

Correct me if I'm wrong, but the minimum specs for WOW is an 800MHz PIII. Remember that they want lots of people paying money so they can play wow, the lower the system specs, the more money they can rake in. I'm pretty sure a 2+GHz celeron is faster then an 800MHz PIII. I doubt its a driver problem as well, both of those cards use the same driver.

Are you sure about the lack of virus? Are you sure there is no performance gain? (don't forget to check the detail settings.) How much of your memory do you have free? Are your AGP settings correct in the bios? (meaning you are running at 8X, not 1X or PCI mode.) Speaking of which, make sure your harddrives are in DMA mode, not PIO.

Lets start here. There is a performance increase, 3DMark showed it. Now we need to figure out why its not showing in the games.

Wow is not very CPU limited, it's more likely intenet-bandwidth limited.

The other thing to remember is that while it may not have appeared to improve much, you may now be actually running much better shaders, instead of the partial-precision or DX8 &lower stuff the FX usually reverts to.

So if it's running all the siny DX9/SM3.0 heavy geomtery or texture load stuff it may be doing 5 times more work, but at the same performance level as before.

I agree with the others, make sure you clean out the old drivers, and then re-install the new ones, but also look at the settings and see if suddenyl it didn't auto detect or set new checkboxes or move sliders to the right.

Personally I lways thought games like WOW were sysem bound, but I don't play them enough to know.

CS:S should be fine with that CPU despite being a Celeron. But a big map or many players may be enough to limit any benefits you notice in your upgrade.

If it is a cedar mill celeron. At that clock speed it could be a Prescott celeron too, with only 256KiB L2.

It seems strange to me cause when i went from FX5600xt(64 bit) to 7600 GS on Athlon XP 3200+ it was almost 300% perfomance increase in WoW.My cpu is limiting my 7600gs only in big cities like orgrimmar or stormwind.So try installing new vide drivers and check temps of cpu maybe it is throttling.

Umm... It's most likely not a driver issue, I used that driver cleaner thing and it didn't change a thing. The BIOS settings are correct too.

The GPU is running at 60 C idle and goes up around 70C on load. The CPU is at 40 idle and about 70 on load as well.
And yes, it's a prescott celeron.

GPU sounds like its running warmer than it should but not to a point that would cause a slowdown. The 7x00 series should run into the 80C+ range without throttling if past experience serves me right. One thing you might look into is a clean install... a lot of work though. The "regardless of video settings" would definitely suggest CPU limiting but there could easily be other factors.

Well i played f.e.a.r on 7600gs at 105 Degrees celsius and had no artifacts which amazed me ) but 70c for cpu is hot, run "Throttle watch" under heavy load to check if it is throttling it may slow down your perfomance in games.
