Using FRAPS: How many FPS should I be getting?

on my PC, I can pretty much run any of the games I own maxed out with top frame rate. when running fraps though, my frame rate always seems to be capped at about 30FPS, no matter what settings I use.

I don't know what sort of frame rate I am supposed to get with my system, so any help would be appreciated.

my specs are:

Windows 7 Professional 64bit
2GB ATI RADEON™ HD 5970
12GB KINGSTON HYPER-X TRI-DDR3 1600MHz, X.M.P
Intel® Core™i7 Six Core Processor i7-970 (3.20GHz)

should I be expecting to be capped at 30ish FPS when recording with FRAPS?

I understand there will be a drop in frame rate. but I'm trying to figure out what the frame rate drop should be for my system.

I've used everything from full screen at 60FPS, down to half screen at 30FPS and all combinations inbetween, still struggles to get above 30, no matter what I choose.

yeah, it dips to about 20-25.

some of the games I have used it with mostly are minecraft, settler 6 and F1 2010. minecraft is not too bad, it usually records at about 45-50FPS, but that's probably because I can get about 200FPS anyway. F1 2010 & S6 are so low that it affects the playability.

MC is usually between 150 & 180

my GPU drivers are already up to date, so there's nothing really I can gain in that area.

oh well, thanks for the advice.
