My system is relatively old. The system slows down as the number of parts in the product increases. My system specs are as follows.
MB : ASUS P5G41T-M-LX3
CPU : Intel Pentium Dual Core E5700 3.0 GHz
RAM : 4GB
There is no dedicated graphics card as of now. So will graphics card like GTX 750 Ti improve my performance or should I go for total overhaul?
Your graphics card will only be able to process what your ram can produce. There is no point maxing out one component with out upgrading the rest of your set up. The gtx is a great piece of kit with great output in both the high and low rpm with a smooth torque curve providing a strong consistent performance. the addition of a forced aspiration system either parasitic or exhaust spun would also help increase BHP but this could decrease average mpg especially on the highway. i don't have a clue what I'm saying best of luck to you
I don't want realistic rendering but just want the software to run smoothly. Any low cost suggestion plesase.
