3D graphics on the "Kepler" class of NVIDIA graphics cards, such as your GeForce GT 620, is currently slow (although I would have thought it would be fast enough for Ubuntu's Unity desktop, but perhaps not given the info you have provided) due to the lack of reclocking support for these cards in the kernel driver. The cards always remain at the slow default clocks which are set during system bootup. The upstream developers are working on this, but it is only in the future 3.8 kernel that they expect to have reclocking support for the older NV50 series of NVIDIA cards (see http://nouveau.freedesktop.org/wiki/CodeNames for an explanation of NVIDIA code names), so support for reclocking your card would not arrive until the 3.9 kernel at the earliest. Unfortunately the 3.9 kernel might not be released until after the release of Ubuntu 13.04. In the meantime you may want to use the binary NVIDIA driver instead.
