|You have to compare the specs of both graphics card. Even if you don't know what certain things mean, you should be able to tell which card is better. Once again, here is a is a link to the specs for a GT 730. Look at them & make sure whatever card you buy meets these same specs.|
GPU Name: GK208
GPU Clock: 902 MHz
Memory Type: GDDR5
Memory Clock: 1253 MHz (5012 MHz effective)
Memory Bus: 64 bit
The memory used on the motherboard (DDR3) is completely separate from the memory used on the graphics card (GDDR5). Please stop obsessing about the amount of memory & just pay attention to the specs. 1GB vs 2GB means nothing, especially on a lower end card. The GT 730 can't make use of 2GB or 4GB memory but some manufacturers install it anyway just to sucker people into buying an inferior card.
Look at the chart (About the GT 730) in the following article, especially the memory bandwidth. Which card has the highest memory bandwidth? That will be the card that will perform the best.
Notice the specs for the card with 128-bit DDR3 memory. Different GPU, lower number of CUDA cores, lower GPU clock speed, etc. Stay far far away from that one.
