Dear friends , recently my four years old AMD duron compatible motherboard expired due to some unknown reasons, and has forced me to plan my total system upgradation. since core2duo proecessors are pricy yet, have planned to upgrade to a pentium 4 processor as of now. But as read about pentium 4 ranges of processors from various articles (digit,CHIP) there are lots of variants of p4....LIKE...p4 E(prescott). p4 EE(extreme edition), P4 HT( hyperthreading.)and also lots of P4 5xx and 6xx series irrespective of clock speeds. i will use this processor for gaming purposes only...and have learnt that P4 EE has 2mb of L2 and 3MB of L3 cache ...will it realy boost my sys. performance. I am really puzzled as want the best processor on P4 series available...and budget is max rs 5000. I have planned to pair it with ASROCK conroe 945 G-DVI motherboard.So, iam looking forward from some detailed expert advises and suggestions to get the best P4 processor (above 3.0 Ghz) considering performance and processor heatinng issue...also if U can add some links.
