It depends on what speed your motherboard can support. If it can only support pc2700 as the fastest speed then yes you can put the 1 gig in their and have it run faster. If the pc3200 (i assume you mean pc 3200 since that is the fastest ddr) came with the pc, then that is probably the fastest your computer will support. You will have 2 options, you can run the pc2700 , or upgrade to 1 gig of pc3200 for better performance.
