I'm building a pc and need a little help. i would like it if i can get some responses on good items with the specs i tell you guys and about how much each piece would cost. i've been looking at newegg for some time and some products i want range from 250 to 400 dollars. im not a genious with the technical stuff but i know well enough and just need help picking out what i need exactly w/o overspending. 1st of all i want a p4 processor about 3.2 or 3.4. Whatever is better for my money but still a higher end chip. i dont want the very best in anything im getting but i want as above avg as i can get w/o spending ridiculous amounts. my budget is about $2,000 but if i can get under that its even better. Next item is the motherboard. i like to stick with what i know or have already and i would like to go with an intel motherboard with ddr2 support, 4gb max mem, hyperthreading and agp slot. i believe the ddr2 mem is the newest mem out so i want the newest in that. and my next item is the memory. is there much difference in speed and cost between 4200, 5400, and 6200 ddr2? and also if i get 1 of these higher speeds is it worth it gettting all 4gb memory chips or is like 2gb well more than enough? next is the hd which i'd like to get as 400gb for storage unless there is mor gb i can get. the cooling system is something im not to familiar wwith. i heard they have liquid cooling systems for $150 or so. are they any good or is a reg fan 1 for $50 good enough. video card i would like at least 256mb card with 1 of the best graphics i can get for my money. sound card i really dont need i have extra ones for that. thanx again for all that help i appreciate it.
