which computer to choose with Pentium processor

hello they are getting rid of the old computer equipment in the office and i have to choose the computer to take home i get first choice to pick.

-15 inch lcd screen 4 gb of ram core 2 duo dual Core E8400 3.00 GHz dvd writer windows vista/ linux

-15 inch crt monitor with 2 gb ram and pentium 4 2 ghz single core HT technology windows xp

hardisks both 250 GB

my friend is telling me to choose the second one Pentium single core HT because he told me it runs faster becuase of HT technology and cooler and consumes less current electricity so it wont get overheated because it has HT technology so it's high definition for encoding and watching HD movies and HD sound and is like a gaming pc to play internet games.

And also he said the dual core 8400 runs at 3 ghz compared to the 2 ghz so it heats very much because of the two extra cores so it takes more current raising electricty bills and is not good for gaming and watching HD movies and internet flash animations and games because of getting heated everytime.

And he wants to choose and take the E8400 because he has air conditioning at home so it will be safe from heating.

So which one computer should i take is it really faster because of the HT High definition technology and will i be able to play internet flash card games better and watch good HD movies Youtube etc and play all the music and songs.

core 2 > pentium - old pentiums produced a LOT of heat, and core 2 era pentiums were low end processors. You'd be stupid not to take the c2d, which is clearly a better system (other than vista :) ) – Journeyman Geek Nov 9 '12 at 11:04

I'd say your friend wants you to take the HT computer so he can have the better one. Either that, or he's just wrong. I don't know your friend so you'd be in a better position to tell if that could be the case. I would definitely take the LCD 4GB c2d 3GHz DVD machine over the HT machine. If only for the fact that it is LCD and 4GB and has a DVD writer. Plus it's a faster machine. You'll be kicking yourself later if you don't. – Kevin Fegan Nov 9 '12 at 11:53
I am sure also, that the 3GHz Dual core 4GB machine will perform better than the 2GHz Single core 2GB machine, hands down. If you're not sure, run a benchmark on both machines first. As for power, probably no more than $0.25 extra/month. Actually, the CRT display will use way more power than the LCD so Core 2 Duo system may use less total power. – Kevin Fegan Nov 9 '12 at 11:58
I'm curious why the question was closed, especially so quickly. OP is not asking if one Brand of computer is better than another. Poster is basically asking abut the difference between two types of processors. With a little editing it could be a solid technical question. – Kevin Fegan Nov 9 '12 at 12:04

Your friend is wrong.

HT means Hyperthreading. Nothing to do with High definition (HD). HT is inferior to dual core.

Of course, low-powered computers use less power and run cooler. Buy something like a $35 raspberry-pi if you want a very low powered PC that can play HD movies.
