I didn't get a very detailed General Spec for my Pc (or i jsut lost it ), but here is what i managed to dig up:
CPU : AMD Athlon II X2 215
2.70 GHz
RAM: 1x 2gb 1066 MHz + 1 extra slot
More detailed : DDR3 - SDRAM (1333MHz)
GPU : Integrated ATI Radeon 3000 (256 MB)
Personal opinion would be that due to lack of RAM or just my PC being totally crappy, Tekkit lags.
What do you think guys ?
