what is your Motherboard?

speaking about CPU alone: depending on the frequency you provided (2.53Ghz) you CPU is Intel® Core™2 Duo Processor T9400, and ir supports Up to 8 GB 667/800 MHz DDR2 or 800/1066 MHz DDR3 SODIMM system memory.
if you tell me about your mobo, we can see the Maximum Memory Supported by your mobo.

well, i wouldn't suggest upgrades now, unless you have enough money ready to be spent on a new PC, upgrade the rams for now.
upgrading the CPU will require upgrading the Mobo and possibly the PSU too.
