Yes, the cards you have are limiting the capabilities of the camera. The K100D does have a limited, 3 frame buffer, so maximum speed capture after the buffer is full depends on a fast card. The K100D is a little bit faster on write speed compared to the *ist DS, far as I could tell from my brief test of one. The Transcend 150x 2G cards are fine: cheap and reliable.
Lexar cards (and flash drives!) have been extremely disappointing to me, with very slow read-write speeds compared to the Sandisk rated the same. The Sandisk Ultra II and Extreme III are very good but a bit on the pricey side. My performance testing of the Transcend 150x and Sandisk Ultra II with the DS body indicated very little real performance gains with the 150x over the 60x cards. While the K100D *might* be a little faster, I doubt it's worth the extra money for the Extreme III. With a fast reader (the Sandisk ImageMate 12-in-1 USB 2.0 is still the fastest I've tested), the Ultra II and T 150x are fast enough on download not to be bothersome either.
