I would like to get a new processor for you computer. Here are my specs right now. Pentium 4 2.6ghz (with Hyper Threading) 1.25 GB of RAM 60 GB-Internal 150 GB-External eVga 7800 GS CO-AGP Edition 450W Power Supply The two processors I was looking at are: Intel Pentium 4 3.0E Prescott 800MHz FSB 1MB L2 Cache Socket 478 Processor with Hyper Threading and Intel Core Duo T2300 Yonah 667MHz FSB 2 x 1MB L2 Cache Socket 478 Processor If cost is not an issue... Which one would give me a greater performance boost? Also if I wanted to spend more would this be any better? Intel Core Duo T2600 667MHz FSB Socket 478 Processor One more question: What is the best thermal paste? People say stuff about as5, what is this and could someone give me a link?
