Upgrade from 1 Gig PC2700 to 1 Gig Dual Channel PC3200??

My current system configuration is as follows:

P4 2.53
Asus P4S800D-X Motherboard
1 Gig single channel PC2700
1 36 Gig WD Raptor
1 120 Gig WD
ATI X850XT 256 MB

My question is would it be worth it to upgrade my ram from the current 1 Gig of single channel PC2700 to the dual channel PC3200? I can currently get a nice dual channel setup from Patriot for about $70 and I'm just wondering if the gain is worth the money. My ram timings are below.

CAS Latency (tCL) : 2.5 clocks @133 MHz, 2.5 clocks @166 MHz
RAS to CAS (tRCD) : 3 clocks @133 MHz, 3 clocks @166 MHz
RAS Precharge (tRP) : 3 clocks @133 MHz, 3 clocks @166 MHz
Cycle Time (tRAS) : 7 clocks @133 MHz, 7 clocks @166 MHz
