Well if u have upgraded, ur graphics card must work better and it does there may be a fault in the graphics card or ur sensors.

Kidfork on this thread i gave you a link to a graphics card performace chart:

Vista forum links, please work :D

Youv replaced the 4350 with a 4550 which is in the same box. Performance will most likely be about the same. Some games may run slightly better but others may run slightly worse.

stew2, your link takes me to the main page of the forum

Not knowing ATI I couldn't tell you much but, the little I know, there are times when you tend to bottleneck your GPU with other resources when you upgrade.

Example: Your PSU is just right for the GPU, then you upgrade the GPU and now, the PSU is no longer able to move the GPU 100% so it lags a bit, hence, your drop on FPSs.

Again, I am not saying this is your problem
