If it's games you want to play, you're not gonna cut it with a GTS 450.

Memory on graphics cards can have two different bottlenecks. The size, and the communication speed aka bandwidth. It's not that easy to just say that 1 GB GDDR5 is the same as 2 GB (G)DDR3.
If your buffer needs to be 1.5 GB, your GDDR5 will bottleneck, despite its faster transfer speed, which means in this case the (G)DDR3 is better.

If you need 120 GB/s of bandwidth, and your GDDR5 memory can handle 128GB/s but your (G)DDR3 can only handle 68GB/s, your (G)DDR3 will bottleneck despite its larger memory size, which means the GDDR5 is better.

Size and bandwidth aren't exactly a direct comparison.

The more memory the card has the more information, such as textures, the card can store locally rather then having to rely on the rest of the system. The speed of the memory effects overall bandwidth, how quickly the card can fill and empty that memory.

If you are looking at two different video cards, list them and your budget, and we can make recommendations.
