BEST SECURITY SUITE THATS NOT A RESOURCE HOG??

I have been using CA Internet Security Suite for the past year or more and my subscription finally ran out last month. I was using The firewall, spyware and virus programs that come with the suite and as well as Adaware and Spybot as secondary scanners. I was quite happy with the Etrust secuurity suite and was going to renew until I found out that CA made a new version for 2007. I treid out the 2007 version and didnt really like it, it seemed to slow my computer down far more than the older version. The 2007 version seems to be a resource hog. Part of the reason I liked the old version so much was thatit was verylight on the resources and worked very well with my older 1ghz Duron 512mb notebook tha I still use almost everyday. The 2007 version slowed it down far to much.
So im gonna go with paid security software. And i need some advice on what to do and which are the best. I have basically two directions I can go in. One is an all-in-one security suite and the second is going with seperate programs for each, firewall, spyware and virus. WHich is the better solution. Also what are the best suites and best seperate virus, spyware and firewall programs?? The features most important to me are low resource usage and good real time protection. Heres the programs im lookingat right nowe

Suites:
Norton 2007 security suite
Zonelabs Security Suite
Panda Securtity Suite
Kaspersky suite

Virus:
AVG
Avast
Mcafee
Kapersky
PC-cillin

Spyware:
Spysweeper
AVG spyware
Counterspy
Spyware Doctor

Any others I should be checking out? Whats everyones opinions?? Should I go for the security suite? Or go with seperaste programs for each spyware, virus and firewall, picking the best for each individual task??
Thanks
