CPU Upgrade

[Winky151]

I'm sure I'm one of the many who use a PC everyday but haven't got a clue about them (got techies at work to fix things). My home PC use is emails, a bit of surfing, the odd excel document & holiday/car show pics (NO gaming at all). Its probably about 10 years old but fine for what I need except currently getting a lot of CPU usage (svchost which I kill the odd thing) but I want to upgrade the CPU anyway. The current one is an Intel e4500. What can I get that will be faster & a straight swap?

TIA
